these plants here look edible i'll pick it to eat later
this food should last a little while
let's raise these animals instead of killing them
good idea then we can get more food once they grow
I'll trade you some wood for some food
People back in the days were really poor and people barely had any food so men went hunting and dying and women went to go pick berries they didn't know were poisonous. Women also had too look out for the babies and killed any animals they found to eat. They didn't have permanent homes so they live in caves.
Sooner or later they came up with a new way to do things without killing animals and dying by animals or poisonous plants. Instead of killing they decided to kidnap animals and raise them instead of killing them. Once the animal produce food they wood go cook it and eat now men don't have to go out and risk their lives for food and women don't have to pick food they don't know if its poisonous or not.
After the people started to learn how to farm the men didn't have to die from animals and women didn't have to die from food poisoning. People also didn't have to live in caves anymore since they now have permanent homes and good food resources and the population starts growing larger and larger.
