Early humans were nomadic and had to adapt to new environments as they migrated. They made adaptations to their diet, learning to hunt, fish, and gather food from different regions. They modified their shelter based on the climate, using animal hides in cold areas and leaves and branches in warmer regions. They also adapted their clothing, wearing animal furs in colder regions and lighter plant-based clothing in warmer areas. Early humans demonstrated resourcefulness and the ability to learn new skills in order to survive in diverse environments.
