Hello Azazel..in a forest environment? you forget the huge advantage a chimp has in being able to climb much faster, more efficiently, go unto smaller limbs and basically hide in the folliage?
Heck, in a forest environment, if the chimp was mad and looking to kill the human, I don't care if the guy gets a rock or a stick- first, chimps have been know in the wild to themselves use sticks as clubs, but second, even if you have a club, you van;t hit it with a club as hard as it could hit you without one, far less with one.
Nah, in a forect the man wouldn't have a chance. NOW, on open ground, thats different.

All of the great apes are substantially stronger than humans. It turns out that a mutation akin to muscular dystrophy, if memory serves me correctly, substantially weakened our ancestors - it's a case of either too many or not enough, I believe too many, of a gene involving muscle strength.
Way too many copies, muscular dystrophy. A few too many copies, and you are less strong, and your jaw muscles are weaker. It turns out that the attachment point for extremely strong jaw muscles up on the skull leads to less cranial capacity. So yes the chimpanzee or any great ape is substantially stronger pound for pound. Also chimpanzees engage in warfare against adjacent groups of chimpanzees, and will exterminate the opposing groups over time. Sounds premeditated to me.

Krazyhorse - I only read a precis of the research, which did not indicate it was isolated to the jaw muscles. However, I am slightly puzzled. Aren't most voluntary muscles going to use the same genes for function/metabolism? Location is going to be determined by embryology and terminator genes - but the base tissue will be the same. How can a gene affect just the jaw muscles and not the other skeletal muscles if it is affecting the base muscular structure/enzymes itself?

quote:
To find out in which tissue the MYH16 gene is normally activated, the investigators examined a wide range of muscle types in the readily available macaque monkey and humans. In macaques, they found the MYH16 protein was only made in a group of related muscles in the head, those involved principally with chewing and biting. In humans, they found that messenger RNA, which translates the genetic code into workaday proteins, was still active in these muscles, but no protein was being made by virtue of the mutation. |
My understanding is that different proteins are used as promoters of growth of otherwise identical tissue in different parts of the body. This is how we can grow different amounts of muscle tissue in different spots. I'm not even close to a biochemist though, so I could be talking out of my ass, but this seems to be what the summary I linked states.

So human beings continue to create the messenger RNA to make MYH16 protein (which promotes muscle development) in the jaw muscles, but due to a mutation MYH16 is no longer created in response to the RNA
