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. But then around 10 or 15,000 years ago, we have the advent of human beings taking nature into their own hands. Instead of saying, let's just follow the game wherever the game might migrate to, let's actually domesticate these animals. Let's take some of them, start breeding them so they're more suitable for human consumption so that they are easier to raise, maybe more robust, and we will breed them, and we will raise them for milk, for meat.
