The evolution of the Alpha?

Anthropology argument against tribal alpha-male narrative
…
There is no good reason to believe that humans evolved in hierarchical tribes between tens of thousands to two million years ago. To the contrary, there is a mountain of evidence showing that humans evolved in largely egalitarian bands that punished attempts of dominance with social sanctioning, banishment, and death (Boehm 1999). Yes, that’s basically saying that alpha males got offed by their social group — not exactly a benefit to reproduction. It appears that human ancestors likely lived in dominance hierarchies sometime in our distant past, but probably prior to the evolution of the hominin (human) line (Boehm 1999; Debreuil 2010). These works indicate that whatever “alpha” dominance tendencies evolved in our remote ancestors has most likely been evolving in the opposite direction for a couple million years.

Evolutionary argument against tribal alpha-male narrative
Without going into tedious detail, it’s unlikely that the alpha-male behavioral type (however imprecise that classification may be) is particularly adaptive. Traits that confer significant reproductive advantage tend to spread through a population rapidly. That basically means that traits that consistently vary widely among a species are probably not under significant selection pressures. If being alpha was the ne plus ultraof mate wooing strategies, there would be a whooooooollle lot fewer “betas.”
