Making the cut ping.
Well, technically speakin’ and all, a lot of this so-called the “cutting edge” training happened when hunter-warrior tribe 1 figgered out that hunter-gatherer tribe 2 was a good target for being on the receiving edge of cutting wedge technology version 1.5 .... And that communicatin’ the need to accurately get the “HELP” back to tribe 1 helped get help from tribe 1 to protect himself as he attacked tribe 2; thus language, writing, speech, etc.
Warfare IS evolutionary: Survival of the fitness requires that the fittest be mentally sharper as well. And, if you are not protecting those already born and those back at the house protecting and feeding your own youth, “you” won’t survive either. Thus, “civilized” behavior of charity, love, and forgiveness are required.
