Forensic facial reconstruction is the process by which a face is reconstructed from a deceased individual’s “skeletal remains through an amalgamation of artistry, forensic science, anthropology, osteology, and anatomy.” This technique is used largely only when skeletal remains are the only evidence at the scene of a crime. Perhaps most famously, it was used in the facial reconstruction of Mitochondrial Eve—but just how accurate is forensic facial reconstruction?

The average person may believe that forensic facial reconstruction is successful and a good proxy for what an individual may have looked like. This is bolstered by the fact that people hear of stories in which facial reconstruction are successful, never hearing of the countless number of cases in which the “reconstruction” fails to identify anyone.

Numerous papers in the literature, though, do show that forensic facial reconstruction does have a high success rate. For instance, Lee et al (2011) and Wilkinson et al (2006) show that this method has a considerable chance of getting facial morphology in the ballpark of how they look. However, this was done on live subjects and is of no use for Mitochondrial Eve/deceased individuals. Facial reconstructions of the deceased are, for the purpose of this article, what we need to look at, not studies looking at live people. (There are also hurdles for facial recognition systems.)

One of the biggest hurdles for the accuracy of forensic facial reconstruction is that average facial tissue thickness cannot be inferred (most importantly, the lips, cartilage, skin and fat). Due to this, with no prior information to look at, the look of the skull will be subjective with the “reconstruction” looking somewhat similar due to chance. Further, the main facial features are largely determined by the shape of the skull.

Now to the fun part: Is this what Mitochondrial Eve really looked like?


There are a number of features that are problematic to infer from these facial reconstructions. Lips, ears, skin, craniofacial muscles—all are extremely hard, or next to impossible, to predict if the only thing we had was a skeleton. Further, since there are few tested relationships between soft and hard tissue for modern humans “it is clear that the use of facial approximation techniques on ancestral skulls of modern Homo are fundamentally flawed, as previously reported by Montagu” (Stephan, 2003). Since soft tissue quickly decays, it is left up to artistic interpretation. Further, attempting to map ape morphology since we diverged a few million years before is misleading, due to the fact that hard and soft tissue relationships are not likely to be the same for apes and our hominin ancestors.

Now that we know the so-called “reconstruction” of Mitochondrial Eve is not what she really looked like, there are a few more problems with this method I’d like to go over.

Forensic facial reconstruction is used when the remains of an unidentified individual are discovered. If the bones of the deceased are all that forensic artists have to go off of, the finished product may be extremely subjective/biased. People who believe that forensic facial reconstruction truly works may say “It works all the time. If it didn’t, how would it be able to solve crimes?” Success rates for the identification of individuals ranges from 50 to 100 percent (Stephan, 2003: 196), and so, the belief that “reconstructions” are largely accurate continue to persist.

However, like with the case of the famous stereotype threat with a modicum of unpublished studies, the “success” of forensic facial reconstruction is also skewed by non-reporting of unsuccessful cases

It is also rare for forensic facial approximation to be to be better than chance, with 403 incorrect facial identifications out of 592 identification scenarios in one study (Stephan and Henneberg, 2001). Facial reconstruction has the greatest accuracy if there is any knowledge of past injuries for the individual,  a photo, and soft tissue. Obviously, in the case of Mitochondrial Eve, we don’t have a photo nor do we have soft tissue and knowledge of past injuries are a non-factor. So it seems that if some people claim to know what the first AMH looked like, it’s probably “just a guess”, and a pretty bad one at that due to the no knowledge of hard and soft facial tissue in the hominin lineage.

The hardest part about facial reconstruction is reconstructing soft tissues accurately since they quickly decompose. This is even more of a problem for people who lived hundreds of thousands of years ago. We’ve never seen any alive so we don’t know what they may have looked like to be able to infer what Mitochondrial Eve would have looked like. Things like lips/mouth, skin, hair, and ears are largely up to artistic interpretation, which are subjective in nature. Craniofacial morphology has also changed in the past 200 thousand years, which may be due to a decrease in testosterone/androgen receptors.

If we can’t identify humans with facial recognition better than chance, what makes anyone think that we can even have the slightest idea of how Mitochondrial Eve looked—when some of the most important parts of the phenotype aren’t around to observe and thus subjectivity then comes into play. Any “reconstructions” you come across, you should take with a grain of salt. It’s next to impossible to know what ancient hominins may have looked like due to the absence of soft tissue, and so any phenotype that a so-called “reconstruction” may give is, largely, up to the interpretation of the individual artist.

With our current technology, it’s next to impossible to ascertain what Mitochondrial Eve—or any other ancient hominin for that matter—may have looked like.

  1. Phil78 says:

    This isn’t even Eve, this is a woman that was part of the 120k exodus to the Levant, specimen Qafzeh 9 to be precise.

    Fairly latter than Eve.


    • RaceRealist says:

      Thanks for the correction. That’s the picture found when searching Mitochondrial Eve in Google.

      The main point stands though: we can’t reconstruct the face of ancient hominin due to lack of hard and soft tissue data. That doesn’t stop ideologues from emphatically asserting that any type of reconstruction of an ancient hominin skull is how they really looked. And, of course, most of the facial phenotype is soft tissue.


    • Phil78 says:

      To RR, I understand an agree. I meant for my correction to actual bolster your point in being limited to understanding what Eve looked like.


    • RaceRealist says:

      PP with the normal standard idiocy, asserting something when he doesn’t know what he’s talking about. PP is a great case study in cognitive biases. He’s the perfect example of the backfire effect.

      the process by which people counterargue preference-incongruent information and bolster their preexisting views. If people counterargue unwelcome information vigorously enough, they may end up with ‘more attitudinally congruent information in mind than before the debate,’ which in turn leads them to report opinions that are more extreme than they otherwise would have had.”

      Even Stephan (2003) writes:

      Additionally, since there are relatively few tested soft to hard tissue relationships currently known for modern humans, it is clear that the use of facial approximation techniques on ancestral skulls of modern Homo are fundamentally flawed, as previously reported by Montagu [4]. The decomposition of the soft tissue parts of paleoanthropological beings makes it impossible for the detail of their actual soft tissue face morphology and variability to be known, as well as the variability of the relationship between the hard and the soft tissue. As a result, the faces of earlier human ancestors cannot be objectively constructed or tested. Attempts based on modem ape morphologies (and variabilities) are likely to be heavily biased, grossly inaccurate, and invalid because the hard to soft tissue relationships of modern apes are unlikely to be the same as hominid ancestors due to changes arising from secular trends and evolutionary forces [4]. Hence any facial “reconstructions” of earlier hominids are likely to be misleading [4].

      PP, is, of course, wrong again.


    • Phil78 says:

      Christ, read his BS on the “negroid phenotype” once again. I “like” how he makes so many appeals to old fashion human taxonomy but obviously knows jack shit of how it works.

      Show him this on the Hofmyer skull showing how it clusters away from modern Sub saharan africans.


    • RaceRealist says:

      It’s incredible. He hand waves away any and all contradictory evidence without even reading journal articles he is provided. I showed that facial “reconstruction” of extinct hominin is very misleading. But because forensic facial “reconstruction” has a “high success rate” then that means we can see what extinct hominin look like?

      No. He’s horribly wrong.
