Australopithecus Afarensis is an extinct hominid which lived between 3.9 and 2.9 million years ago. This type of hominid was the first type to develop bipedalism, or walking on the  hind legs. Also, they developed the feature of having opposable thumbs for hurling stones and sticks at predators. Australopithecus Afarensis were herbivores and did not create or utilize tools in their lifestyle. Australopithecus Boisei could not adapt to their environment well at all, which led to their extinction. Australopithecus Boisei also had very little imagination and did not use tools in their lifestyle. Homo Habilis was the first hominid to carry the genus name Homo. Homo Habilis, meaning Handy Man or man the skillful, added meat to their diet, which lead to the sharing of food among themselves. Homo Habilis used Oldowan tools, the oldest known tools used by hominids, by chipping stones to create sharp edges. Homo Ergaster, also known as Homo Erectus, changed to the Archulean stone tool industry. Archulean tools have a bifacial, symmetrical cutting edge, with a distinct tool form that can be repeated. Different shapes of Archulean tools were used for different purposes. Homo Heidelbergensis used fire to scare away predators and harden tools. Heidelbergensis used their environment for more than just food purposes, but they still had no imagination. Neanderthalensis used stone tools, wore clothes, and developed a language of some sort. Neanderthalensis were almost completely carnivorous; they never ate fish or berries or vegetables. Homo sapiens, or modern humans, became more wise with more developed brains and had imagination and a social structure.

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.
