What caused the early primates to evolve into modern people?
About 7 million years ago, the African apes were established by the Sahelanthropus Tchadensis, the common predecessor of the chimpanzees and humans, departing from the rest of the "big apes", including orangutans and gorillas. Large apes show forms of culture and communication beyond their own bands or tribe and can engage in behavior such as empathetic social fraud, indicating the theory of mind. Sahelanthropus Tchadensis is considered to be the oldest hominin ancestor related to modern people. Hominins include both chimpanzees and people, while the family homo refers to human ancestors after divergence from chimpanzees. We are scraped on accurate terms, because there are little fossil evidence of chimpanzees because they lived in the rainforest environment where bones are not well preserved. Australopithecus was the first group of human ancestors to whomThey used to go upright.
homo habilis , the first member of the family homo , lived 2.4 to about 1.5 million years and was the first user of the tool. The use of simple uniform stone tools has reduced the load on the teeth and the stools decreased accordingly. Social organizations became more complex, with larger bands on average allowing mutual cooperation, but also intensive cooperation in cooperation for friends and dominance. The throwing of the spear has developed and as the game became more rare, the members of Homo were forced to migrate around, even abandoned Africa about 2 million years ago, when Sahara became even dry and larger than usual.
One of the biggest drivers of humming was sexual selection and violence - if one group of early people could attack another band, kill all men and connect with all women, their genes would be handed over to the next generation. It is important to have too pinkOr an idealistic view of man evolution, because it is not the way that things really work. Our diet has also become less specialized because we have adapted to the full use of hunting and collecting in obtaining our nutrients.
About 250,000 years ago, homo sapiens finally appeared to produce advanced hand axes and "redesigned" stone tools, allowing him to survive in a wide range of environments and spread around the world.
