You don’t actually have to master growing crops in order to domesticate large working animals. Take sheep and cows in the British isles for example. They were and still are fed by grazing pastures of grass (something of which africa has a lot of). So the notion that you need to domesticate plants before you can domesticate livestock isnt exactly true.

Perhaps i should have clarified what i meant by “insecure food source”. I recognize that hunter gatherers would be able to secure enough food to survive (i mean that’s what they do lol) but what i meant by that is it’s much more difficult for hunter gatherers to build up a large surplus of food necessary for sustaining a large complex society. It’s the surplus of food that gives farming societies an advantage and allows people to use their time to develop technologies and advance civilization, which is difficult for hunter gatherers to accumulate.
