    The “spandrel hypothesis” is the front runner explanation. Essentially we didn’t evolve to have chins but rather evolved other things that are helpful, and the chin is a byproduct of that other evolution. Not harmful so it didn’t get selected away, but not helpful.

    Well, you can’t take it on the chin if you don’t have one I suppose.

    I figure walking upright made being hit from below more common, necessitating thicker bones to protect the very sensitive nerves of the jaw.

    Artificial Intelligence Analysis:

    The chin is situated near the area where the tongue and jawbone interact during speech. It’s possible that the chin provides a surface for the tongue to move against, allowing for more complex sounds and articulations. The development of language is believed to have occurred around the same time as the emergence of Homo sapiens. While other primates have similar facial structures, they don’t possess a distinct chin. This suggests that the chin might be related to the unique demands of human language.

    Bingo – other animals don’t have a chin because they didn’t invent languages like humans did for communication, and thus the demands of speaking weren’t evenly distributed.

    Next time on interesting questions 104: Why did homo sapiens develop language when other animals such as Corvids did not?

      I do lick my chin a lot when articulating language. As we all do, right…? fellow humanoids ?

      This makes more sense than the need to put on pillow cases (which has been my prevailing theory up to this point), but your question about corvids intrigues me. Partially because I’m not entirely certain of what a corvids is.

    I read somewhere sometime ago that the theory that makes the most sense is that we evolved chins to take a punch, which animals besides our immediate evolutionary relatives do not do.

    So we evolved chins as an evolutionary advantage over our immediate evolutionary relatives who would logically be competing for the same resources.

      I read something at some point about how our fists seemed to have evolved or at least adapted to be well suited to delivering a punch. Many people do not use proper hand forms for it, but I suppose it’s a learned skill if not at least through trial and error.

        Great, now I have a scenario in my head where one early human delivers a punch and dies of having not the right hands and the other dies because no chin. Also: Imagine our fists if there had been more habsburgs.

    If I am not mistaken, according to the grammatical scrolls, having a chin makes everyone … chinese
