Question: 1 / 400

What role did social behavior play in the development of early hominins?

It discouraged competition

It enhanced group survival and cooperation

Social behavior among early hominins significantly enhanced group survival and cooperation, which were critical for their adaptation to various environments. Living in groups allowed early humans to share resources, protect each other from predators, and collaborate in hunting and gathering food. This cooperative behavior likely facilitated the development of complex social structures and established stronger community bonds.

In groups, individuals could take on specialized roles, share knowledge about food sources, and care for offspring, thereby increasing the overall fitness of the group. Cooperative breeding and shared parenting are examples of how social structures benefited early hominins, promoting survival in challenging conditions. This ability to work together effectively would have provided a substantial advantage over solitary living, making social behavior a key factor in the success and evolution of early human species.
