I have been an avid reader and interested in astronomy/space ever since I could remember. I remember really loving Stephen Hawking and his documentaries on black holes. I would read anything I could find on constellations and stars. From there I went on to reading sci-fi. I then recall seeing The Martian Chronicles by Ray Bradbury and from then on I had become interested in sci-fi writing. But, as I grew older, I drifted away from sci-fi and now only read non-fiction. Then when I got older I got into ‘HBD’ (chronicled here) and along with it evolution—but, unlike other ‘HBDers’ I became enamored with the work of Gould, while some of my favorite books come from him. Gould wrote a lot about evolutionary contingency—the degree to which an outcome could be different. Evolutionary contingency is a big topic in philosophy of biology, and Bradbury has a great short story on this type of contingency.
Ray Bradbury is an interesting author—one who has many short stories and regular books. One of my favorite stories from Bradbury is one called A Sound of Thunder which chronicled a time machine company who let people go back in time to hunt any animal they’d like—if you want to take down the ancestor of a whale before it became aquatic, just name the place and they will send you there. They were told to only stay on the path laid out by the time machine company—animals they could shoot were marked with red paint, presumably those animals would have died anyway so killing them would not change any outcomes. The text from Bradbury is worth quoting in full, as it wonderfully captures the thought of evolutionary contingency:
He indicated a metal path that struck off into green wilderness, over streaming swamp, among giant ferns and palms. “And that,” he said, “is the Path, laid by Time Safari for your use, It floats six inches above the earth. Doesn’t touch so much as one grass blade, flower, or tree. It’s an anti-gravity metal. Its purpose is to keep you from touching this world of the past in any way. Stay on the Path. Don’t go off it. I repeat. Don’t go off. For any reason! If you fall off, there’s a penalty. And don’t shoot any animal we don’t okay.”
“Why?” asked Eckels.
They sat in the ancient wilderness. Far birds’ cries blew on a wind, and the smell of tar and an old salt sea, moist grasses, and flowers the color of blood.
“We don’t want to change the Future. We don’t belong here in the Past. The government doesn’t like us here. We have to pay big graft to keep our franchise. A Time Machine is finicky business. Not knowing it, we might kill an important animal, a small bird, a roach, a flower even, thus destroying an important link in a growing species.”
“That’s not clear,” said Eckels.
“All right,” Travis continued, “say we accidentally kill one mouse here. That means all the future families of this one particular mouse are destroyed, right?”
“And all the families of the families of the families of that one mouse! With a stamp of your foot, you annihilate first one, then a dozen, then a thousand, a million, a billion possible mice!”
“So they’re dead,” said Eckels. “So what?”
“So what?” Travis snorted quietly. “Well, what about the foxes that’ll need those mice to survive? For want of ten mice, a fox dies. For want of ten foxes a lion starves. For want of a lion, all manner of insects, vultures, infinite billions of life forms are thrown into chaos and destruction. Eventually it all boils down to this: fifty-nine million years later, a caveman, one of a dozen on the entire world, goes hunting wild boar or saber-toothed tiger for food. But you, friend, have stepped on all the tigers in that region. By stepping on one single mouse. So the caveman starves. And the caveman, please note, is not just any expendable man, no! He is an entire future nation. From his loins would have sprung ten sons. From their loins one hundred sons, and thus onward to a civilization. Destroy this one man, and you destroy a race, a people, an entire history of life. It is comparable to slaying some of Adam’s grandchildren. The stomp of your foot, on one mouse, could start an earthquake, the effects of which could shake our earth and destinies down through Time, to their very foundations. With the death of that one caveman, a billion others yet unborn are throttled in the womb. Perhaps Rome never rises on its seven hills. Perhaps Europe is forever a dark forest, and only Asia waxes healthy and teeming. Step on a mouse and you crush the Pyramids. Step on a mouse and you leave your print, like a Grand Canyon, across Eternity. Queen Elizabeth might never be born, Washington might not cross the Delaware, there might never be a United States at all. So be careful. Stay on the Path. Never step off!”
“I see,” said Eckels. “Then it wouldn’t pay for us even to touch the grass?”
“Correct. Crushing certain plants could add up infinitesimally. A little error here would multiply in sixty million years, all out of proportion. Of course maybe our theory is wrong. Maybe Time can’t be changed by us. Or maybe it can be changed only in little subtle ways. A dead mouse here makes an insect imbalance there, a population disproportion later, a bad harvest further on, a depression, mass starvation, and finally, a change in social temperament in far-flung countries. Something much more subtle, like that. Perhaps only a soft breath, a whisper, a hair, pollen on the air, such a slight, slight change that unless you looked close you wouldn’t see it. Who knows? Who really can say he knows? We don’t know. We’re guessing. But until we do know for certain whether our messing around in Time can make a big roar or a little rustle in history, we’re being careful. This Machine, this Path, your clothing and bodies, were sterilized, as you know, before the journey. We wear these oxygen helmets so we can’t introduce our bacteria into an ancient atmosphere.”
This passage from Bradbury wonderfully illustrates evolutionary—historical—contingency. Things could have been different—this is the basis of the contingency argument. The universe does not repeat itself—if we were to replay the tape of life we would get a completely different outcome—Lane (2015) states maybe octopi would rule the earth? We could replay the tape of life, have it go exactly as it did to lead up to today, change ONE SEEMINGLY MINISCULE THING (say, stepping on a bug that did not die) which would then cascade throughout history leading to a change in the future. Evolution is full of passive trends, with no indication that—for example with body plans—that there is a drive to become more complex—it is passive (Gould, 1996: 207):
All the tests provide evidence for a passive trend and no drive to complexity. McShea found twenty-four cases of significant increases or decreases in comparing the range of modern descendants with an ancestor (out of a potential sample of ninety comparisons, or five groups of mammals, each with six variables measured in each of three ways; for the other comparison, average descendants did not differ significantly from ancestors). Interestingly, thirteen of these significant changes led to decreases in complexity, while only nine showed an increase. (The difference between thirteen and nine is not statistically significant, but I am wryly amused, given all traditional expectation in the other direction, that more comparisons show increasing rather than decreasing complexity.
Gould first put forth his contingency argument in Wonderful Life—any replay would be different then the next. Gould critiqued the increasing complexity claim, arguing that diversification is always accompanied by decimation—once a mass extinction (say, an asteroid impact) occurs, there will then be subsequent diversification after the decimation.
We have no idea why certain organisms persisted over others after periods of decimation—and ‘adaptation’ to environments cannot be the whole story. Out of all of Gould’s writing that I have read in my life, this passage is one of my favorites as it perfectly captures the problem at hand:
Wind the tape of life back to Burgess times, and let it play again. If Pikaia does not survive in the replay, we are wiped out of future history—all of us, from shark to robin to orangutan. And I don’t think that any handicapper, given Burgess evidence as known today, would have granted very favorable odds for the persistence of Pikaia.
And so, if you wish to ask the question of the ages—why do humans exist?—a major part of the answer, touching those aspects of the issue that science can treat at all, must be: because Pikaia survived the Burgess decimation. This response does not cite a single law of nature; it embodies no statement about predictable evolutionary pathways, no calculation of probabilities based on general rules of anatomy or ecology. The survival of Pikaia was a contingency of “just history.” I do not think that any “higher” answer can be given, and I cannot imagine that any resolution could be more fascinating. We are the offspring of history, and must establish our own paths in this most diverse and interesting of conceivable universes—one indifferent to our suffering, and therefore offering us maximal freedom to thrive, or to fail, in our own chosen way. (Gould, 1989: 323)
Contingency is about counterfactuals—what could have happened, what could have been, or what would have been had some certain condition changed, with everything before that occurring as usual. Bradbury’s A Sound of Thunder wonderfully illustrates the contingency of the evolutionary process—change one seemingly small, minuscule thing in the past and this could snowball and cascade to huge changes in the future—we may never have existed or we would have existed but have been radically different. If we could go back in time and, say, crush a butterfly and see the changes it would have made, we could say that the event that caused the future to change was the crushing of that butterfly—this could have, eventually, led to the non-existence of a certain group of people or a certain group of animals which would have radically changed the outcome of the world—both the natural and human world.
So, if we could replay life’s tape from the very beginning, I do believe that life as we know it would be different—for if we played it from the beginning, we could have a scenario as described by Bradbury—everything could go exactly the same with one small seemingly minuscule change snowballing into a world that we would barely recognize.
I was watching the program Diagnose Me on Discovery Health and a woman kept having seizures whenever she heard a certain type of music—“alternative high-pitched female singing”, according to the woman—but her doctors didn’t believe her. So her and her husband began looking for specialists who specialize in hard-to-treat epilepsy. He recommended an endocranial EEG (images of such a surgery can be found below), which meant that the top part of her skull would be removed and electrodes would be placed onto the top of her brain. After the electrodes were placed on the brain. they played the music she said triggered her epilepsy—which was “high-pitched female singing”—and she began to seize. The doctor was shocked and he couldn’t believe what he saw. They ended up finding out that a majority—not all—of her seizing was coming from the right temporal lobe. So her and her husband had a choice—live with the seizures (which she couldn’t because she did not know where she would hear the music) or get part of her brain removed. She chose to have part of her right temporal lobe removed and when it was removed she no longer seized from hearing the music that formerly triggered her symptoms.
The condition is called “musicogenic epilepsy” which is a rare form of what is called “reflex epilepsy”—of which, another similar form involved hitting something which then causes seizing in the patient. (It’s called “reflex epilepsy” since the epileptic events occurs after an event—music, hitting something with your foot, seeing something on the television, etc.) This occurs when certain types of music are heard, certain musical notes can trigger electrical brain activity. The cure is to remove the part of the brain that is affecting the patient. (It is worth noting that many individuals throughout the past 100 years have had large sections of their brains removed and had no loss-of-functioning, staying pretty much the same as they were.) It is important to note that the music is not causing the seizures, it is triggering them—it brings them out. Most of the seizing is localized in the right temporal lobe (Kaplan, 2003), further being localized in Heschl’s gyrus (Nagahama et al, 2017). This has been noted by a few researchers since last century (Shaw and Hill, 1946; Fujinawa and Kawai, 1978) while the Joan of Arc was said to have her perception scrambled while hearing church bells; a Chinese poet stated that he became “absent-minded” and “sick” when hearing the flute-playing from the street vendor (Murray, 2010: 173).
The condition was first noted by a doctor in 1937, with the first known reference to this form of epilepsy being observed in the 1600s (Kaplan, 2003: 465). It affects about 1 in 10,000,000 people (Ellis, 2017). Critical reviews state not to underestimate the power of anti-epileptic drugs in the treatment and management of musicogenic epilepsy (Maguire, 2012), but in the case described above, such drugs did nothing to cure the woman’s seizures that occurred each time she heard a certain kind of music. The effect of music on seizing, it seems, is dichotomous with certain kinds of music either helping manage or causing seizing. The same melody, however, could be played in a different key and not cause seizing (Kaplan and Stoker, 2010) and so, it seems that certain types of sound frequencies influence/screw up the electrical activity in the brain which then leads to seizures of this kind. A specialist in epilepsy explains:
In people with reflex epilepsy, the trigger is extremely specific, and the seizure happens soon thereafter. “It can be a specific song by a particular person or even a specific verse of the song,” says Dr. So, who is a past president of the American Epilepsy Society. For some people, the trigger is a touch or motion. “If patients are interrupted in a particular way, if they are walking along and someone steps in front of them, they may have a seizure,” says Dr. So. In Japan, seizures caused by video games have been reported, he says, but they are highly unusual.
Dr. So evaluated a woman from Tennessee who began having seizures during church when she heard highly emotional hymns. She would blank out and drop her hymn book. At other times, Whitney Houston’s “I Will Always Love You” triggered seizures. The woman had a history of small seizures, but having one while hearing music was a new development. She said the seizures would typically begin with a sense of dread and the feeling that someone was lurking by her side. Dr. So and his Mayo Clinic team attached electrodes to the woman’s scalp to study electrical activity while she listened to different types of music. An electroencephalogram (EEG) showed that slow, emotional songs triggered seizure activity in her brain’s temporal lobe, while faster tunes did not. Dr. So diagnosed the woman with musicogenic epilepsy, a type of reflex epilepsy where seizures are caused by specific music or types of music, and prescribed antiseizure medication. He says he’s had another patient whose seizures were triggered by Rihanna’s “Disturbia” and Pharrell Williams’ “Happy.”
Though musicogenic epilepsy is extremely rare, it may be slightly underreported since many people with the disease may not put two and two together and link their seizing with the type of music or sounds they hear in their day-to-day life. One individual with epilepsy also recounts his experience with this type of rare epilepsy:
… but I still find that certain music, high pitched noise set’s off a kind of aura, I feel spaced out, have intense fear and it sounds almost like water rushing and I hear voices.
One case report exists of a man in which his later seizures were induced by music which prompted stress and a bad mood, implying that the aetiology of musicogenic epilepsy involves an association between the seizing and the patient’s mental state (Cheng, 2016).
We can see how the endocranial EEG looks and how it gets done (WARNING: GRAPHIC) by referring to Nagahama et al (2019):
Intraoperative photographs demonstrating exposure and intracranial electrode placement. A right frontotemporoparietal craniotomy (A) allowed proper exposure for placement of grid, strip, and depth of electrodes (B), including the HG depth electrode. The sylvian fissure is marked with a dashed line. The HG depth electrode and PT depth electrose are marked with X symbols anteriorly and posteriorly, respectively, at their entry points at the cortical surface. Ant = anterior; inf = inferior; post = posterior; sup = superior.
Intraoperative placement of the HG depth electrode. A: The planning view on the frameless stereotactic system (Stealth Navigation, Medtronic) showing the entry point and the trajectory (green circles and dotted lines). B: The similar planning view showing the target and the trajectory. C and D: Intraoperative photographs showing placement of the HG depth electrode. A Stealth Navigus probe was used to select the appropriate trajectory of a guiding tube positioned over the entry point (C). An electrode-guiding cannula was advanced through the tube to the previously determined depth (D). An actual depth electrode was subsequently passed through the cannula, followed by removal of the guiding tube/cannula system. Note the unique anterolateral-to-posteromedial trajectory within the STP for placement of the HG depth electrode.
The average age of onset of musicogenic epilepsy is 28 (Wieser et al, 1997) while the first cases are not reported until around one’s mid-to-late 30s due to the fact that most people are unware that music may be causing their seizures (Pittau et al, 2008; Generalov et al, 2018). This may be due to the fact that seizing may begin several minutes after hearing the music that affects the patient in question (Avanzini, 2003). While the specific tempo and pitch of music seems to have no effect on the beginnings of seizing (Wieser et al, 1997), many patients report that their specific triggers are due to hearing certain lines in songs (Tayah et al, 2006) which implies that it is not the music itself which is causing the seizing, but the emotional response that occurs to the patient after hearing the music and this is supported by the fact that many patients who report such symptoms are interested in music or are musicians themselves (Wieser et al, 1997).
See table 1 from Kaplan (2003: 466) for causes of musicogenic epilepsy in the literature:
As can be seen by the above table, the mood component is related to the musical type; so the music elicits some sort of emotional state in the individual which would, it seems, to be part of the cause which then triggers the seizure—though the music/emotions are not causing the seizing itself, it is bringing them out.
Going to the shops was fraught with danger. Turning on the television was like playing russian roulette. Even getting into a lift was a gamble. For 23 years my life was hugely restricted because I had epileptic fits whenever I heard music.
If it was more than a few notes, a strange humming would start in my head, immediately followed by a seizure. I didn’t fall to the ground and twitch, but would wander around in a daze, my heart racing, my mind a blank. I also experienced hallucinations: people around me appeared microscopic and it felt as if I had been captured by an invisible force field. It was a terrifying experience and I felt drained for hours afterwards. (Experience: Music gave me seizures)
One woman describes her experience with musicogenic epilepsy for The Guardian. She did everything she could think of to stop the music-induced seizures—from sticking cotton balls into her ears to stop hearing sounds, to staying inside of the house (in case a car driving by played the type of music that triggered her seizing), to having a silent wedding with no music. She ended up getting referred to a specialist and she got her brain checked out. Come to find out, she had scarring on her right temporal lobe and so, surgery was done to fix it. She was cured from her condition and she could then attend social functions in which music was played.
The brain has the capacity to produce electricity, and so, in certain individuals with certain things wrong with the structure of their brains (like in their right temporal lobe), if they hear a certain kind of music or tune, they may then begin seizing. While the condition is rare (around 150 cases have been noted), strides are being made in discovering how and why such things occur. The only cure, it seems, is to remove the affected part of the brain—the right temporal lobe in a majority of cases. Such operations, however, do not always have the same debilitating effects (i.e., causing loss of mental capacity). That the brain’s normal functioning can be affected by sound (music) is very interesting and speaks to the fact that our brains are an enigma which is just beginning to be unraveled.

Unless you’ve been living under a rock since December 2019, you should have heard the panic that SARS-CoV (which causes COVID-19—coronavirus disease) is causing ever since it emerged in Wuhan, China (Singhal, 2020). This virus spreads really easily—though asymptomatic transmission is thought to be rare, according to the CDC. There is one case report, though, of an infant who showed no signs of COVID-19 but had a high viral load (Kam et al, 2020). In any case, Trump flip-flopped from calling it a ‘hoax’ to taking it seriously, acknowledging the pandemic. “I’ve felt it was a pandemic long before it was called a pandemic“, Trump said. Ah, of course, It must have been just a facade to say it was a hoax. (Pandering to his base?) The ever prescient Trump knows all.
Speaking of prediction, Cheng et al (2007) stated “The presence of a large reservoir of SARS-CoV-like viruses in horseshoe bats, together with the culture of eating exotic mammals in southern China, is a time bomb. The possibility of the reemergence of SARS and other novel viruses from animals or laboratories and therefore the need for preparedness should not be ignored.” Quite the prediction from 13 years ago—implicating southern China’s “culture of eating exotic mammals”, which is more than likely the origin of this current outbreak.
There has been some discussion on whether or not the coronavirus is “as bad” as they’re saying, which has been criticized, for example, for not bringing up the context-dependency of the numbers. The number of cases in the US, though, as of Friday, March 20, 2020, was at 15,219 with 201 deaths. The number of cases keeps increasing daily. As of 3/22/2020, America has had 26,909 cases with 349 deaths while 178 recovered. Ninety-seven percent are in mild condition right now while three percent are in serious condition.
The current recommendations—social distancing, self-quarantining—are what we are doing to fight the virus, but I think we are going to need more drastic measures. Social distancing and self-quarantining will help to slow the spread of the virus, but the virus is still obviously spreading.
All of the talk about what to call it—Wuhan virus, Chinese virus, China virus, coronavirus—is irrelevant. Call it whatever you’d like, just make sure that whomever you’re communicating with knows what you’re talking about. (And, if you want to ensure they do, just call it “coronavirus” as that seems to be the name that has stuck these past few months.) I understand the want to identify where it began and spread from, but of course, others will use it for racial reasons.
The past few days there has been a lot of attention focused on hydroxychloroquine (HCQ) and azithromycin. These are anti-malarial drugs; a trial was done to see if it would have any effect on COVID-19 (Liu et al, 2020).
For HCQ, there is an “expert consensus” on HCQ treatment and COVID-19, and they state:
It recommended chloroquine phosphate tablet, 500mg twice per day for 10 days for patients diagnosed as mild, moderate and severe cases of novel coronavirus pneumonia and without contraindications to chloroquine.
HCQ and chloroquine are cellular autophagy modulators that interfere with the pH-dependent steps of endosome-mediated viral entry and late stages of replication of enveloped viruses such as retroviruses, flaviviruses, and coronaviruses (Savarino and others 2003; Vincent and others 2005).
I don’t know what to make of such results, I am awaiting larger trials on the matter. There is some hope in using anti-malarial drugs in the hopes of curbing the disease.
The Chinese knew that this virus was similar to other SARS strains, their scientists were ordered to stop testing on samples and to destroy the evidence. (See here for a timeline of the case.) The scary thing is that this virus has symptoms similar to the common cold that we get every winter so some may brush it off as ‘just the cold.’ I came down with a cold at the end of January and I was out of commission for the week. Thankfully, it was not COVID-19.
Italy and China had a strong trade relationship, which seems to have cost Italy. Italy has one of the oldest populations in the world. Ninety-nine percent of corona deaths in Italy, though, had other health problems, such as being obese, having hypertension, previous heart problems, etc. Italy began locking down cities as early as two weeks ago, though they have reported a staggering 4,825 deaths. This, though, is to be expected when a quarter of the country is aged 65 and older with multiple comorbidities. So if it is that bad in Italy with a smaller population, what does that mean for the US in the coming weeks?
New York and New Jersey banned gatherings of more than 50 people, dining out, gyms, etc in an effort to curb the transmission of the virus. Then, Friday night at midnight (3/21/2020) only essential businesses were allowed to stay open—essentials include healthcare, infrastructure, food (no dining-in, take-out or delivery only), grocery stores, mail, laundromats, law enforcement, etc. In NJ, all businesses were ordered to close down except things like grocery stores, banks, pet stores, convenience stores, etc. This affected me (gyms closed) and so I cannot work. I preempted this a few weeks ago and found a job in logistics, but I got laid off on Friday due to the shut-downs of nonessential businesses (the shut-downs decreased my work). Now, I’m thinking about hunkering down until at least June. Due to what we know about the social determinants of health (Marmot, 2005; Cockerham, 2007; Barr, 2019) we can expect what is associated with low class (poor health, stress, etc) to increase as well.
This is only going to get worse in the coming weeks. I do see a decreased number of people out on the street, and I am glad that states are taking measures to curb the transmission of the virus, but I still see people not really taking it seriously. From the ads on the radio informing us about what is going on around the country in terms of death rate and transmission rate, they are strongly suggesting for people to stay home and to avoid public transportation. Obviously, in places that are enclosed and many people walk in and out in a timely manner, that is a great place for the virus to spread. ….what if we’re doing what the virus ‘wants’? Don’t worry, the evo-psychos are here to tell us just-so stories.
By this account, COVID-19 is turning out to be a remarkably intelligent evolutionary adversary. By exploiting vulnerabilities in human psychology selectively bred by its pathogen ancestors, it has already shut down many of our schools, crashed our stock market, increased social conflict and xenophobia, reshuffled our migration patterns, and is working to contain us in homogenous spaces where it can keep spreading. We should pause to remark that COVID-19 is extraordinarily successful epidemiologically, precisely because it is not extremely lethal. With its mortality rate of 90%, for example, Ebola is a rather stupid virus: It kills its host — and itself — too quickly to spread far enough to reshape other species’ life-ways to cater to its needs. (The Coronavirus Is Much Worse Than You Think)
Ah, the non-lethality of COVID-19 is to its benefit—it can spread more, it is an “intelligent evolutionary adversary” but it is causing a “moral panic” as well. The damage to our psyche, apparently, is worse than what it could do to our lungs. And while I do agree that this could damage our collective psyches, we don’t need to tell just-so stories about it.
When we come out of this pandemic, I can see us being very cautious as we go back to normal life (in places affected, people are still going out where I live but not as much). Then, hundreds of years later, Evolutionary Psychologists notice how averse people are to go outside. “Why are people so introverted? Why do people avoid others?” They ask. “Why are those who wear masks more attractive than those who don’t wear masks?” They then discover the pandemic of the 2020s which ravaged the world. “Ah! Critics won’t be able to say ‘just-so stories’ now! We know the preceding event—we have a record of it happening!” And so, the evo-psychos celebrate.
In all seriousness, if people do take this seriously, there may be some social/cultural customs changes, including how we greet people.
Cao et al (2020) conclude: “The East Asian populations have much higher AFs [allele frequencies] in the eQTL variants associated with higher ACE2 expression in tissues (Fig. 1c), which may suggest different susceptibility or response to 2019-nCoV/SARS-CoV-2 from different populations under the similar conditions.” Asian men smoke more cigarettes than Asian women (Ma et al, 2002, 2004; Chae, Gavin, and Takeuchi, 2006; Tsai et al, 2008). In your lungs you have what is called “cilia fibers’ and these fibers move debris and microbes out while they also protect the bronchus and trap microorganisms. COVID-19 attacks these same cilia fibers that degrade when one smokes. Therefore, the fact that East Asian populations have higher allele frequencies in ACE2 expression tissues along with higher rates of smoking may be why Asian men seem to be affected more than Asian women. In any case, smokers of any race need to exercise caution.
What if after the pandemic is over life does not go back to normal? What if life during the pandemic becomes the ‘new normal’ when the pandemic is over because everyone is paranoid about contracting the virus again? For introverts, like myself, it’s easy to lock-in. I have hundreds of books to choose from to read, so if I do choose to lock in for 2 months (which I am thinking about), then I won’t really be bored. But my thing is this: what’s the point of locking in when everyone else isn’t, the virus still spreads and when you finally go out the pandemic is still going on? The point of quarantining is understandable—but if everyone doesn’t do it, will it really work? Libertarians be damned, we need the government to step in and do these kinds of things right now. It’s not about the individual, but the public as a whole.
On the other hand, it is thought-provoking to think about the fact that the government is ramping up the drama in the news to see how far they can go with social control. What a perfect way to see how far the public would go if they got “suggestions” from the government. Just like the government is “suggesting” we be inside at 8 pm to mitigate viral transmission, for example, it’s just to see what we would accept and how far they can go until they make it mandatory. It is interesting to think about how all of the toilet paper, hand sanitizer, hand soap, etc are being sold out everywhere.
People in my generation have 9/11 to look back to as the “That’s when the world changed” time. Well, kids alive today (around 7-15 years old) are experiencing their “9/11”, as that’s when the world changed for them. But this coronavirus pandemic is not on a country level—it is on the world level. The whole WORLD is affected. So since our Gregorian calendar is based off the birth of Jesus, I propose the following: change 1-December 2019 AD/CE to BC (before Corona) and anything after December 2019 to AC (after Corona).
I hope that, looking back on the current goings-on now that we are not talking about high death tolls and that we can get this under control. The only course of action (for now) is to attempt to stop the transmission of the virus—which is to stop its transmission from human to human. COVID-19 can be said to largely be a social disease since that is how it is most likely to be transmitted, which is why social distancing is so important. Being social is how the virus spreads, so to stop spreading the virus we need to be anti-social.
If we do not heed these warnings, then we will permanently be living in the Time of Corona. Coronavirus will be dictating what we do and when we do it. No one will want to get sick but no one will also want to take the steps needed in order to eradicate the threat. This thing is just getting started, by the end of the month into the first few weeks of April it is only going to get worse. I hope you all are prepared (have food [meat], water, soap, etc) because we’re in for a hell of a ride. With many businesses closing down in an effort to curb the transmission of COVID-19, many people will be out of jobs—many low-income people.
Biology is one of the most interesting sciences since, at its core, it is the study of life and living systems. The biological organization of living systems and the ecosystems these living systems find themselves in are interesting to learn about, since we can then discern different species and learn how and when to delineate separate species based on a set of pre-conceived measures. The classification of human races in these systems will be discussed, along with why human races are not different species.
The organization of living systems
Living systems show hierarchical organization, each system—from the physiological to the physical—interacting with each other. However, a key factor in the organization of these interactions is the degree of the complexity of the interactions in question. We can look at the organization of the biological world as hierarchical—that is, each level builds on the preceding level, so we get from atoms to the biosphere and everything in between is what we call “life” and also show how these complex, living biological systems live and exist due to the hierarchical organization of living systems. The point is, life does not have a simple definition, but all living systems share similar characteristics that can describe life. Biologists organize living systems hierarchically, from the subcellular level to the entire biosphere, and then study the interactions that occur which cannot be predicted from just studying the sum of its parts. This is why a holistic—and not reductionistic—approach needs to be taken when studying and describing living systems.
The hierarchy is:
The cellular level, which includes: atoms, molecules, macromolecules, and organelles; the organismal level which include: tissue, organs, the organ system, and the organism; the populational level which includes: the population, species, and the community; and finally the highest level, the ecosystem level which includes the ecosystem and the biosphere.
At the cellular level, we have atoms which are the fundamental elements of matter and are joined together by chemical bonds called molecules. large and complex molecules are called macromolecules, DNA—which stores hereditary information—is a type of macromolecule. Complex biological molecules are then assembled into organelles, where cellular activities are organized. A mitochondrion is, for example, an organelle with a cell that extracted energy from consumed food molecules. And finally, we have cells, which are the basic unit of life.
Next, we have the organismal level, and cells of multicellular organisms make up three levels of organization. Tissues, which are groups of similar cells which function together as a unit. Tissues then are grouped into organs which are structures of the body which are composed of many different kinds of tissues which act in a structural manner and as a unit. Then we have organ systems, such as the nervous system which is the sensory organs, brain and spinal cord, and the network of neurons that convey signals to different parts of the body.
Then we have the populational level. This includes the individual organisms which occupy various hierarchical levels in the biological world. A population is a group of organisms all living in the same place. Together, all populations of a particular kind form a species—members of a species must look similar and be able to interbreed. Then finally, we have the biological community which consists of all of the populations coexisting together in one place.
Lastly, we have the ecosystem level. This is the highest tier of biological organization (the lowest being the cellular level). A biological community and its physical habitat (such as soil composition, available water etc) in which it finds itself in and lives and competes with other organisms constitute an ecosystem while the entire planet is the highest of all levels of biological organization—the biosphere. All of these systems together can be seen as the hierarchical organization of living systems.
(See Mason et al, 2018 for more discussion of the above points.)
Now, in these differing biological hierarchies, we find differing Eukarya, Prokarya, and Bacteria. The in-use classification system is the Linnean hierarchy. Differences exist between organisms, this is obvious. But it is a bit more tricky to classify these organisms and place them into like groups. Then, in the 1750s, Carolus Linnaeus came along and instituted a binomial classification system for organisms—the most commonly-known binomial being Homo sapiens—which was much simpler than the polynomial names
The hierarchy is as follows:
7. Kingdom; and
8. Domain. Domains can then be split into Archaea, Bacteria, and Eukarya. Domains are the largest taxons, being that they comprise every organism that we know of.
For example, our species is sapiens, our genus is Homo, our family is Hominidae, our order is primates, our class is Mammalia, our phylum is Chordata (with a subphylum Craniata), our kingdom is Animalia and our domain is Eukarya. This is our species’ taxonomic classification.
The traditional classification system—the Linnean system—groups species into genera, families, orders, classes, phyla, and kingdoms. Thus, these systems classify different organisms on the basis of similar traits, and since they consist of a mix of derived and ancestral traits, they do not necessarily take into account different evolutionary relationships.
There are of course limitations to the Linnean hierarchy:
1) Many “higher” taxonomic ranks are not monophyletic and so do not represent real groups (like Reptilia). For something to be a “natural group”, a common ancestor and its descendants must all derive from descent from a common ancestor, so any other type of taxonomic ranks are created by taxonomists, such as paraphyletic and polyphyletic.
2) Linnean ranks are not equivalent. Two families may not represent clades that arose at the same time, because one family may have diverged millions of years before the other family and so the two families had differing amounts of time to diverge and acquire new traits. So comparisons in the Linnean sense may be misleading and we should then use hypotheses of phylogenetic relationships.
What is a species?
It should first be noted that species are, indeed, real. New species arise when isolated organisms of one population become genetically/geographically isolated for a period of time. Over time, as the split population spends time geographically and genetically isolated, they cannot interbreed with the parent population and thusly attain separate species status. This is the received view, the biological species concept.
There are a wide range of species concepts and they all capture the differences that different theorists believe we should emphasize in our classification of organisms.
The phenetic species which appeal to the intrinsic similarities of organisms. The biological species concept which appeals to reproductive isolation (one version of the biological species concept is the recognition concept, which defines species as a system of mating recognition. The cohesion species concept which generalizes the biological species concept and it recognizes that gene flow isn’t the only factor that holds a population together and makes it different from other populations. The ecological species concept which defines species by appealing to the fact that members of a species are in competition with one another because of the need the same resources. And the phylogenetic and evolutionary species concept which define species as segments on the tree of life (the phylogenetic species concept, for instance, holds the term ‘species’ should be reserved for groups of populations that have been evolving independently of other populations.
Sterelny and Griffiths (1999) tackled this in their book Sex and Death: An Introduction to Philosophy of Biology:
While we think cladism presents the best view of systematics, biological classification nevertheless poses an unsolved problem. If we were to accept either evolutionary taxonomy, which builds disparity into its classification system, or phenetic taxonomy, which is based on the idea of nested levels of similarity, traditonal taxonomic levels would be quite defensible. Within those taxonomic pictures, the idea of genus, family, order, and so on makes quite good sense. If cladism is the only defensible picture of systematics, the situation is more troubling. From that perspective, these taxonomic ranks make little sense. Cladists do not think there is a well-defined objective notion of the amount of evolutionary divergence. That, in part, is why they are cladists. Hence, they do not think there will be any robust answer to the questions, when should we call a monophyletic group of species a genus? a family? an order? Only monophyletic groups should be called anything, for they are well-defined chucnks of the tree. But only science greets the question, are the chimps plus humans a genus? It has long been receieved wisdom in taxonomy that there is something arbitrary about taxonomic classification above species. These decisions are judgement calls. So cladists only show a somewhat more extreme version of a skepticism that has long existed. The problem of high taxonomic ranks would not matter except for the importance of the information expressed using them. Hence cladism reinforces the worry that when, for example, we consider divergent extinction and survival patterns, our data may not be tobust, for our units may not be commensurable. Unfortunately, it does this without suggesting much of a cure.
Where does race fit in?
Racehood is simple: A race is a group of humans that: Condition 1; is distinguished from other groups of humans by patterns of visible physical features; Condition 2: is linked by common geographic ancestry which is peculiar to members of this group; and Condition 3: originates from a distinctive geographic location.
So now all we need to do is go through four steps: 1) recognize that there are patterns of visible physical features which correspond to geographic ancestry; 2) observe that these patterns of visible physical features which correspond to geographic ancestry are exhibited between real, existing groups; 3) note that these real existing groups that exhibit these patterns by geographic ancestry satisfy C1-C3; and 4) infer that race exists.
Some may argue that the races are different species, citing the same patterns of visible physical features discussed above. However, if we are referring to the biological species concept, then the human races are not different species at all since all human races can produce fertile offspring with one another. Our genus, of course, is Homo, all of the human races are the same genus; though some may attempt to use the previously-discussed conditions for racehood as conditions for specieshood for humans, the most preferred method for delineating species currently is the biological species concept, and since all of the human races can produce fertile offspring then the human races are not different species.
In keeping with the classification system that is currently used today (see above), where would human races fit into our taxonomy? Falling within our species sapiens seems like a good start, and since the races can interbreed and have fertile offspring, then they are not different species but are the same species, despite phenotypic differences. Thus, human races would be within species but under subspecies. Using this line of logic, human races cannot be different species, despite claims to the contrary that human races are different species based on patterns of visible physical features which correspond to geographic ancestry. That’s enough to denote racehood, not specieshood.
The study of life—in all of its forms and in all of its environments—is one of the most important things we, as humans, can do. From it, we can learn where we came from and even—possibly—where we may be going. Once we understood the biological hierarchy and how upper levels are built from lower levels working together, then we were better able to understand how living systems act on the inside—cellularly and physiologically—to the outside—organismal and environmental interaction. From organismal and environmental interaction, speciation may occur. The highest level of the organization of living systems is the biosphere—and it is so because the living systems that are driven by the smallest cellular interactions interact with other species, the ecosystem and the biosphere.
Species do exist, but there are numerous species concepts—over twenty. One of the more popular species concepts in use is the cladistic species concept. In this species concept, a species is a lineage of populations between two specific branch points. The cladistic concept thusly recognizes differing species by differing branch points and how much change occurs between them (see Ridley, 1989).
The classification of different organisms into different species is pretty straightforward, though it falls prey to oversimplification since it only focuses on similar traits. Species exist, this is established. But races are not species, contrary to some beliefs. Different races can interbreed and, I would argue, that for there to be separate species, human races would not be able to interbreed. Yes, there are physical and morphological differences between races, but, as argued, this is not enough to denote speciation, but it is enough to denote raciation.
