Describe three ways in which stone age humans adapted to their environment during the last ice age

In the Stone Age, people lived in groups. Every group of Stone Age people had hunters and gatherers. The hunters had to provide meat. because they already figured out how to build/make a fire they started cooking meat, therefore their jaw evolved from larger to smaller because they no longer had to eat raw meat. They also started to make clothing from animal skins because it was really, really, really cold after the last ice age.

Hope this helps out.
