Maybe the bulk of humans seem more like their monkey selves. Perhaps some people have gotten beyond the monkey selves (not that the primate is utterly wrong or unworthy) and have begun exploring the other animals within, so to speak. Maybe the people who seem more like wolf-people and less like monkey-people have just looked at embracing a different...societal pattern. Perhaps what it comes down to is that some monkey-people have decided not to cower as omegas, nor to they want to bully as alphas, so they look at other patterns in the jungle/forests/whatever and find a pattern that suits them. Therefore, you wind up with people who act more like cats, more like dogs or wolves, more like birds.

I know my share of monkey-people who think they're something else. And perhaps on the surface, they've created this exterior that appears to be something else. But deep down, they're still monkey-people and either cowering or bullying.
