> There was a time you could just walk out and pick it off trees. For some, yes. Others you had to hunt or catch. > Food didn't change. We did. If you mean the human population grew to a point where simple hunting and gathering could not support it, and then food changed after that, that's getting things backwards. Our ancestors invented farming, i.e., a new way of producing food, and then the population grew larger than hunting and gathering could support. So food changed first. Then we changed. > You must always ask: Progress towards what? Yes, agreed. Not everyone would consider our ancestors' invention of farming to be progress, for example.
