Which evidence suggests that early humans practiced cooperation?

The presence of shared hunting tools and organized campsites provides substantial evidence that early humans engaged in cooperative behavior. This suggests a social structure where groups of individuals worked together for mutual benefit, which is essential for survival. Shared hunting tools indicate a system where knowledge and resources were pooled, allowing for more effective hunting strategies and increased success in obtaining food. Additionally, organized campsites imply planned communal living arrangements where individuals could support each other, share responsibilities, and care for one another, further reinforcing the notion of cooperation in early human societies. This collaborative approach would have been crucial in adapting to environmental challenges and securing food resources in a way that individual efforts alone could not achieve.
