But it's definitely no influence on whether or not there's dinner tonight. Humans became their own livestock. They domesticated themselves. Breeding is minimising chance, and going from hunter to pastoralist is like going from dice to poker- from no control to some, if you play your cards right. But what came next was like opening a savings account.
Humans are omnivores.
The forest monkey in our lineage gave us the ability to eat fruits, seeds and certain leaves, and the plains-ape stage added meat. Meat was necessary because the only things on the plains were animals and grass, and apes can't eat grass. Or couldn't, until someone at some point discovered that certain grass seeds could be ground up, mixed with water and fat and baked into bread. At first, grass seeds must have been gathered opportunistically, like berries, but when the science of eugenics was established in pastoralism, it was only a matter of time before it spread to plants, in particular to a certain prized species of Middle Eastern wheat. Humans now could not only eat grass, but by domesticating it, they could create their own permanent pastures - farms.
