Theory:

Social Life: Social ties facilitated humans' survival.

Our forefathers were able to meet their societies' everyday demands by sharing food, caring for children, and forming social networks.
 
Early humans started to congregate around hearths and shelters to feed and socialise over time. Growing up took longer as brains became more extensive and more complex, necessitating more parental care and a safe atmosphere. They were expanding social networks that ultimately contributed to modern humans' complex social lives.
Sharing resources:
Some early human communities started gathering tools and food from different locations and transporting them to favourite resting and eating locations. Sharing valuable resources with other group members reinforced social ties and improved the group's survival chances.
Kanjera, Kenya, evidence:
Early humans transported stone up to \(12\) kilometres to a site in Kanjera, Kenya, around \(2\) million years ago. They carved stone tools for butchering animals there. Smithsonian scientists have excavated stone tools and slaughtered animal bones at Kanjera with colleagues from Kenya and the United States.
