The food was obtained through hunting of animals and gathering of certain plants. This meant that they had to have nomadic lifestyle in order to have enough food to survive, and their migrations were dictated by the migrations of the animals and the seasons. This was putting the early humans at big risk constantly, as there were lot of predators that were able to take them down with ease, such as big cats, canids, ancient bears, hyenas, and even the animals that they were hunting were extremely dangerous, especially the mastodon and mammoth. In order to be safer and more effective in getting food, they lived in groups, and were spending the nights in caves, rock shelters in cliffs, and in retractable tents, usually located at good locations for defending.
