The big lizard.
Seriously, I do so recognize 'alphas.' They're people whose 'internal lizard' drives them to seek the highest spot on the rock, to fight for dominance, etc.
I suppose I should expand that a bit: People are part lizard, part monkey. The lizard part is concerned with hierarchy; the monkey part is interested in play.
Among the lizards, 'alpha status' is the only thing. I spot the would-be 'alpha humans' by their posturings. It's not subtle stuff.
Spotting (human) alpha males and alpha females isn't at all difficult. Lizards spend GOBS of energy on display. So do people. And, to make it easier, lizards and humans alike tend to engage in display at specific locations. People who are mostly lizard have an easy time finding places where they can do . . . that lizard thing.
I define 'AlphaMale/Female' as 'people I'd just as soon see dead.' They really aren't my kind of monkey.
