Humans can selectively breed for dominance just as animals have been bred for it.

Evidence

Where do high SDOs come from? The smart money will bet on the interaction of genes and environment. We should take the genetic prospects quite seriously. Virtually all animal societies are built around dominance systems and humans have been able to breed aggressive, dominant behavior in some species, and greatly reduce it in others. Hence cock and bull fights; hence our docile lab rats. — John T. Jost and Jim Sidanius, Political Psychology, 1065
