Organisms compete with other organisms for resources in order to survive. Humans got too good at it having a higher intellect, plus we can breed year round.
Brainiacs say we gain an upright gait first ... which allowed us to simply walk off with the leopard's kill and eat it in our place of safety ... it was after our brains got bigger ... our main advance is our horrific taste, nothing eats us ... which allowed us to climb down from the trees and develop an upright gait ...
Early humans were easy prey for the medium-sized predators ... they just couldn't stomach us except as carrion ... and the older the better ...
