    They want to remove bias and increase accuracy of artistic depictions of extinct hominids. What is the beef?

    Bias? By the way, I like that -- "increase accuracy." But now that you mention it, accuracy? What do you mean by that?

    It's pretty interesting how a subjective decision can make some interesting differences in the reconstruction of the facial appearence of an extinct hominid.

    Doesn't "accuracy" in that context always translate to "closer to reality". In facial reconstruction there is always going to be a measure of interpretation since you are going by skull shape and muscle lines which leaves a lot of room, but there are ways to increase accuracy by using more sophisticated modeling tools taking into account more data or by removing entirely a completely imagination dependent feature like hair style as mentioned in the article.

    Accuracy in the artistic representation.

    yup. :) It sure is. Interesting. Of course, beauty (and by that I mean physical beauty) can be "in the eyes of the beholder." Although decisions have been made about what constitutes physical facial beauty.

    They aren't trying to make them pretty. They are trying to reconstitute the appearance of a dead person based on his or her bone.

    The one on the left is modelled after using chimps muscles as a baseline while the other, on the right, is using modern human muscles as baseline to reconstitute the appearance of that child.

    And if I understand you correctly, it seems you are saying many renderings were not accurate?

    Yeah, we don't want no ugly reconstructions.

    Some people think chimps are cute, maybe not pretty though. Muscles, however, are usually not preserved in skull fossils, are they?

    They are interpretations that can vary with the artist and basis they follow in making the reconstruction. I am not applying any quantitative estimates on the number and level of accuracy of any rendering. I actually read and understood the article you linked.

    You spoke of bias. Yet fail to explain.

    Did he mention that original muscles are preserved in these fossils? I did not see him mention that.

    No beef. Just reconstruction by ?? scientific methods or artists employed by publications? Meantime, the article states, "Now, the researchers that produced the dueling images are attempting to remove some of this subjectivity by introducing standards that may give more accurate and reproducible portraits of species known only from fossilized bone." So -- may give more accurate ...portraits." I like the term "may give." May give. After a long time. Well, science changes, doesn't it? :) Wait a minute. Now I see no hair on these rendered faces. LOL, they lost their facial hair -- :)

    I'm asking. Since a poster was including muscles of chimps as a baseline.

    The muscles themselves are not, but all muscles leaves marks and imprints on bones where they were attached and its by analyzing those marks that you can know their shape and their mass at least to a certain degree.
