The development of early hominid societies was encouraged by a combination of factors such as the ability to use tools, increased brain size and cognitive abilities, improved communication skills, the establishment of social hierarchies, and the development of fire usage. These changes allowed hominids to adapt to new environments, find new food sources, protect themselves from predators, and collaborate more effectively within their communities.
