The Evolution of Man

[Polar]

Another theory on human evolution regarding hand usage.

Primates are known to be less accurate than us in regards to throwing motions and lessened dexterity. Humans have less muscles in their fingers (barely at all), and primates tend to have more muscles within their distal joints. This definitely could contribute to greater grip strength (for body size) in primates, and in return, less accuracy in dexterity when it comes to manipulating an object. However, their grips are probably more coordinated than ours (we don't swing through branches like they do), so when it comes to building weapons with slow precision we win. When it comes to making a fast, split-second decision in forcefully-grabbing a stationary object without manipulation, primates rule. Not to mention, primates might have a microscopic muscular advantage over us which makes their muscle fibers much stronger than ours.

Again, this is just a personal theory. Anyone have any thoughts about this? I will look into further research regarding the evolution of both primate and human hand structure. Reply
