After cannibalizing the males and taking more than 100,000 Neanderthal females as war captives, Saps took all his domesticated animals and raised his children as their slave caste.
Homo Sapiens likes spearchucking, rape, cannibalism and fighting. He doesn't have the brains, patience or persistence to do difficult things like domesticating animals. All he needs is a can of beer and sports jersey and he's happy, being not much brighter than a shiny red button.
Those brains he stole with gang rape of Neanderthal females is fading fast. Saps is going back to that mud he came from.
Saps is a weak imitation of a real human. The real humans were the Neanderthals. Saps is just a pale shadow and he only has any tenderness in his heart at all for animals because he has a couple genes from 'Thals he acquired from rape. Like the ghoul who temporarily takes on the characteristics of those he eats, Saps has felt himself to be a man for a short while during the Holocene but this glamour won't last much longer.
