How did prehistoric hunter gatherers increase their food supply?

Prehistoric hunter-gatherers increased their food supply through various strategies, including the development of tools for more efficient hunting and gathering, such as spears and fishing nets. They also practiced seasonal migration to follow animal herds and access different plant resources. Additionally, they engaged in foraging techniques that maximized the intake of edible plants, nuts, and fruits, and began to form social groups that enhanced cooperative hunting and sharing of food resources. Over time, these practices laid the groundwork for the eventual transition to agriculture.
