Bones in the face brake the easiest simply because they are in a vulnerable position.
No bones break easiest in the face because they haven't evolved to withstand punishment. Just like rams face doesn't break so easily. Because it has
evolved to take abuse to the face. Humans, all primates have sexual dimorphisim. Humans too. The difference in robustness in male facial bones
could be due to a vestige of being a primate. In fact humans have less sexual dimorphisim than previous versions of hominids. We lost a lot of
sexual dimorphisim through the evolution of the homo genus not gained it. So the scientists theory is crap right there.
Generally male primates have larger check bones due to having larger jaw muscles that needed to attach to the sagittal area. not to withstand more
blows than another male to the head. We as humans have actually lost most of our dimorphisim not gained it by getting punched in the face.
Men have bigger noses then women? Last time I looked they are they same size.
Jaws break easy. It sure appears that our jaw did not evolve to withstand any sort of force to it other than what it was designed for. They pop out
of socket too easily too. Wouldn't the ascending ramus be reinforced where it attached near the mastoid process to minimize this happening? It
doesn't seem any more developed then what would be accounted for by basic sexual dimorphisim.
Regarding the necks. The longer the neck the more angular momentum is driven to the brain. Animals that evolve to not get knocked out so easily have
shorter necks to minimize that. Wouldn't males have shorter necks to mitigate this?
SO they have bigger jaws, shorter necks, stockier bodies and went on to out mate the rest of the neighboring population to become the dominate
specimen on the earth. Tell that to the Chinese. I sure don't see a lot of dudes looking like Sylvester stallone running around there. Short stalky
guys with fred flinstone bodies and the face of Arnold schwarzenegger are running the human race? Seems the opposite happened to me.
I don't think the chicks had so much a choice in who they mated with in cavemen times. There was the alpha male. He got that way by beating up the
other guy. Probably not from out smarting him in a game of social chess. Getting a broken bone in the face doesn't stop Og from mating, probably not
even in the long run. Thats a modern thing. He regardless of how he looked after the fight was the victor and did whatever the hell he probably
wanted and whomever the hell he wanted. Kinda how it works in the animal kingdom. How's a broken face going to stop the guy from procreating,
especially when it probably wasn't up to the women. "Ewww you're ugly....oglana no wanna" "yeah, what's your point, bend over? Ooog!!! ooog!!!
ooog!!!"
Ever thought for a second that males from one group of humans had bigger jaws then males from another because of what they ate. Gorillas have huge
jaws. Massive sagittal areas, massive zygomats to allow passage of large muscles. All of that not to withstand blows to the face. because hardness
isn't really the deciding factor. But because they needed the muscle power to out chew their rivals and out eat them. You know. Group A has tougher
food to chew than group B. hence the evolution of tougher jaws. Exquisite!
