Early humans interacted through verbal communication, gestures, and possibly rudimentary forms of writing or drawing. They also formed social groups to share resources, provide protection, and engage in cooperative activities such as hunting and gathering. These interactions helped early humans survive and thrive in their environments.
Early humans had smaller brains, used primitive tools and lived as hunter-gatherers. They did not have advanced technology or complex societies like we do today. Additionally, early humans may have had different physical characteristics, such as a more robust build and different facial features.
The use of remnants as containers helped early humans store and carry food, tools, and other essential items, which was crucial for survival. It enabled them to transport resources more efficiently, making hunting, gathering, and moving to new environments easier. This innovation likely also helped in organizing resources and planning for future needs.
