Actually I am not sure. That is not my area of expertise. But lets say that it does lead to warfare. So what? As I just pointed out the God of the Bible is far worse.
Skyscrapers, culture, cars, airplanes, business models are also things or activities that are engaged in by people. But they are not genetic traits or the endpoints of evolution.
Certainly, some populations may have genetic traits that predispose them more aggressive or more peaceful positions, but trying to tie any human outcome regardless of what it might be to evolution is another attempt to equate it to a belief system in my opinion.
It also seems indicative of a low level of understanding of biology, human behavior and the theory of evolution.
That a person may be born with the musculature and physiology that have distinct fitness advantages in some environments doesn't mean they will become an athlete or take up a particular kind of athletics. Those are more akin to side-effects and repurposing of existing evolved traits.
I disagree and think you are qualified to come a similar conclusion, given what I know of your understanding of these things. It is just such a weird claim that a valid answer isn't immediately obvious.
