They also improved their tools: they added handles, for example, to improve their efficiency; they invented the rope, fishing hooks, whistles, baskets.
In the cold areas, they needed animal skins to cover themselves and to hunt better; they invented the spear, the bow; and, to separate the flesh of the
skin, better burins, chisels and flint knives.
