Lions, Gorillas, Chickens etc. all have unique approaches to management of intra-group conflicts. Lions have their prides with only one dominant male. Gorillas have similar arrangements. Roosters don’t stay to play Dad — guess mother hens like to be in control. In so far as ability to write and philosophize is concerned, neither of lions, nor gorillas, or chickens possess man’s intellectual awareness, yet they have intricate, interesting, unique approaches to management of intra-group conflict.
Point is, in light of the evidence, achievement of intellectual awareness, the essence of man’s dominance, cannot be attributed to presence of systems for management of intra-group conflict.
For scientific evidence that man’s arrival at intellectual awareness occurred within the time frame of Creationism, that is, only within the last 5,000 years or so, check out this piece authored by me.
I am not saying you are wrong, but the evidence you cite is flawed. It may be helpful to check out some of the evidence from the Creationists’ side of the origins debate.
