Agri-culture. For most of human history over this Paleolithic period, over most of this timeline going up until about 10,000 or 15,000 years ago, our ancestors were hunter-gatherers. They would have to chase the game wherever it might be. They couldn't settle down in one place. Maybe there were a few that were near some sources of fish where they might be able to do some basic fishing, but they would have done hunting like this. They would have done gathering, which means getting berries or mushrooms where they could find it. It probably was eating a lot of things like insects, and that is most of human history.
