Hominids (early humans) and Technology.
Among them were our early human ancestors who started to make stone tools by this time. The other line seems to have lived more in mixed grassland and woodland environments, like the earlier australopithecines, and was primarily vegetarian. This second, more conservative line of early hominins died out by 1 million years ago or shortly before then. It is likely that all of the early hominins, including humans, supplemented their diets with protein and fat rich termites and ants just as some chimpanzees do today.
Homo Habilis finds out how to make fire and how to use it: cooking, keeping wild animals away, hunting, having heat.
Homo Sapiens made boats, nets, and started fishing. The fish were a good source of food and vitamins for the sapiens.
Later, groups of hominids appeared about 3 million years ago. As time passed, they became more modern humans.
By 2.5 million years ago, there were at least 2 evolutionary lines of hominins descended from the early australopithecines. One line apparently was adapted primarily to the food resources in lake margin grassland environments and had an omnivorous diet that increasingly included meat.
As the australopithecines evolved, they exploited more types of environments. Their early proto-hominin ancestors had been predominantly tropical forest animals. However, African forests were progressively giving way to sparse woodlands and dry grasslands, or savannas click this icon to hear the preceding term pronounced. The australopithecines took advantage of these new conditions. In the more open environments, bipedalism would very likely have been an advantage.
During the Ice Age, humans lived in caves because of the very low temperatures, probably because of boredom, they started drawing, later on, this was the source of many beliefs and taboos.
The first tools were made around 3 million years ago. (by Homo Habilis) how they were made: The homo Habilis were hitting a rock against a bigger rock until it was shaped like a tool.
By 3 million years ago, they were common in both East and South Africa. Some have been found dating to this period in North Central Africa also.
The primate fossil record for this crucial transitional period leading to australopithecines is still scanty and somewhat confusing. However, by about 4.2 million years ago, unquestionable australopithecines were present.
Sahelanthropus was the earliest species of hominids, dating 7-6 million years ago. Orrorin lived about 6 million years ago, while Ardipithecus remains have been dated to 5.8-4.4 million years ago.
The Homo Sapiens started using tools, and made farms, it was a good way to get food but they traded what they couldn't eat. They also bred animals.
