Tribal warfare is man-made so by definition is not natural. Evolutionists don't appreciate the central role that tribal warfare plays in human evolution and that humans are not a product of nature but of envious murder and war. Natural selection is not a significant factor in the evolution of modern humans, nor in the foods we like to eat. Almost all human-specific traits and culture, such as religion, can be traced to their advantage in war. Modern humans are not the natural masters we like to think, and the theory of evolution as popularly described does not add up. The cynics have valid points.
Women, in general, prefer tall men. This is an example of “sexual selection” which is also part of “natural selection”. The fact that it is female humans doing the selecting and not female peacocks doesn't make it any less “natural”.
Evolutionary Biologists have long recognized the role of violence in human evolution. There is no doubt that among all the apes, we are the most carnivorous, the most violent, and the most murderous. Those changes are understood by Evolutionary Biologists to have come about via evolution through natural selection of genetic variation. And yes, natural selection includes war.
The theory as “popularly described”, as understood by you ( or MIS-understood by you); may well not “add up”. But that is a lack of your understanding, not a lack on the part of the theory.
War is a Darwinian activity. It is how the weak get eliminated and massive gene transfer takes place.
Progressive pacifists are weak and will be overcome. Since their women are ugly, the gene transfer will be dampened
