Study: Male Facial Development Evolved To Take Punches

First time accepted submitter Joe_NoOne (48818) writes "A new theory suggests that our male ancestors evolved beefy facial features as a defense against fist fights. The bones most commonly broken in human punch-ups also gained the most strength in early hominin evolution. They are also the bones that show most divergence between males and females. From the article: 'Fossil records show that the australopiths, immediate predecessors of the human genus Homo, had strikingly robust facial structures. For many years, this extra strength was seen as an adaptation to a tough diet including nuts, seeds and grasses. But more recent findings, examining the wear pattern and carbon isotopes in australopith teeth, have cast some doubt on this "feeding hypothesis". "In fact, [the australopith] boisei, the 'nutcracker man', was probably eating fruit," said Prof David Carrier, the new theory's lead author and an evolutionary biologist at the University of Utah. Instead of diet, Prof Carrier and his co-author, physician Dr Michael Morgan, propose that violent competition demanded the development of these facial fortifications: what they call the "protective buttressing hypothesis".'"

Random steps can take a locally deleterious feature a long way "up hill" in terms of fitness before it gets lost entirely from the population, and that process may well carry it over into a new local minimum that was deeper than the one it drifted out of.

    That said, there are quite likely strong constraints on facial morphology that put limits on armouring. The human face is extremely important as a communications device, and remember: selection is driven by the differential probability of getting laid and creating successful offspring (where "successful" means... "getting laid and...")

    So for example, blood flow in the face is a very important communications tool. There is reason to believe that the whole point of human's red/green colour acuity is so that we are maximally sensitive to variations in blood flow in each others' skins, particularly in the face. So variations that substantially reduced that already-subtle signalling channel would plausibly reduce the chance of those individuals getting laid.

    Likewise, facial flexibility and mobility are important aspects of communication between humans (and likely proto-humans), and so on. Because we are by nature social primates, the effective communication goes beyond simple mate competition, too: the ability to form viable troops, work together cooperatively, etc, all will affect the individual's reproductive fitness, particularly when kin-selection is factored in (my genes will go on if my siblings and cousins are successful at mating, even if I am not, so my contributions to their success matters in the evolutionary process.) [Of course, there are also completely kooky speculative ideas about group selection, which are fun to play with: http://www.amazon.com/Darwins-...

If you actually let kids use their jaws to chew stuff instead of cutting everything up and swapped out much of the carb load for more fat and protein you'd see a dramatic change in the populations facial structure.

Boxer's fractures are a thing of th evolutionary past.

    It's just hard to buy that punching exerts such a dramatic evolutionary pressure on various anatomical features and leaves the fist something a person has to be *taught* to make properly, and which *still* tends to injure itself while punching without the benefit of gloves or taping.

    It seems more plausible that the response of facial development to the presence of testosterone is a matter of *sexual* selection than survival based selection, that humans evolved to hit with clubs and rocks and that fists are a less critical corner case. People who come up with these theories evidently don't have much experience hitting things with their bare hands, which is not surprising given that they've got these handy opposable thumbs.

  43. News: Tony Abbott evolved a punchable face by David+Gerard · · Score: 1

    OLDUVAI GORGE, Warringah, Monday (NTN) — A new theory suggests that Tony Abbott's ancestors evolved remarkably punchable facial features, accounting for people's deep desire to do so today.

    The bones most commonly broken in prehistoric Liberal Party punch-ups gained the most strength in early "conservative" evolution. They are also the bones that show most divergence between Liberals and Nationals.

    The paper, in the journal Guardian Australia, argues that the reinforcements evolved amid fighting over females and resources, in which communication by kicking each other's heads drove key policy changes.

    Fossil records show that Australopithecus menzieii had strikingly robust facial structures. This was long seen as an adaptation to a tough diet including nuts, seeds and Malcom Turnbull's balls. But more recent findings suggest that violent intra-party competition was the cause: the "protective buttressing hypothesis".

    Interestingly, the evolutionary descendants of Australopithecus — including more left-leaning humans — have displayed less and less facial buttressing. "Human arms and upper bodies are not nearly as strong as those found in Liberal Party members," said the author, Prof David Carrier, dusting off his gloves.

    Studies from Canberra emergency wards show that faces are particularly vulnerable to violent injuries, many self-inflicted from being banged against desks when Coalition policy proposals reach the news.

    "The historical record goes back a short time, but anatomy holds clues as to what selection was important, what behaviours were important; and so it gives us important information about what caveman notion Mr Abbott is going to come out with next."

    You're underestimating the ability of the mammalian eye to withstand and recover from damage. Remember that LASIK surgery doesn't even bother with stitches, for example. And practically speaking the amount of force and accuracy required to drive a weapon or tool through an eye socket isn't much less than what's required to puncture the thinner parts of the skull.

    I've been stabbed in the eye with a pencil, hard enough that it lodged in the socket behind the eye until I yanked it out, and had one of my eyes gouged far enough out that it was briefly laying on my upper cheek. Because of that I am at a higher than normal risk for glaucoma, but everything healed up fine years ago. Eyes are remarkably tough! The biggest danger to them is generally infection, not blunt trauma. Although if you actually pop one, they don't always refill without medical intervention, so do try to avoid that.

    As for selection processes, remember how much of our brain appears to be optimized for facial recognition - even at birth - and consider how much being recognizable might improve one's chance of being sexually selected. :) That could provide some of the competing constraints you theorized.
