Return to History 8 Human Origins Concepts The social development of hominids has changed greatly because of early hominids adding meat to their diet and evidence is found in different parts of the world.. For example, about 2 million years ago, early humans transported stone up to 12 km (7 mi) to a site at Kanjera, Kenya. They made stone tools for butchering animals. Stone tools excavated from Kanjera chemically match rocks found at natural sources up to 12 km (7 mi) away. Early humans carried the tools from these distant places, probably stopping and using them along the way. So, this shows that the tools were shared amongst other hominids, which shows that they cared for one another. Early humans began to gather at shelters to eat and socialize. As brains became larger and more complex, growing up took longer, requiring more parental care and the protective environment of a home. Expanding social networks led, eventually, to the complex social lives of modern humans. Beginning at 2.6-1.8 million years ago some groups of early humans began collecting tools and food from a variety of places and bringing them to favored resting and eating spots. Sharing vital resources with other members of the group led to stronger social bonds and enhanced the group’s chances of survival.
