human+evolutiion

Hi, I am going to be talking to you about human evolution. Human evolution was believed to have started 45 million years ago. They are believed to have originated in Africa and moved around to different contents during the last ice age. They are believed to have moved away from Africa between 100,000 years ago and 40,000 years ago. Humans, apes, and monkeys all share a common ancestor. Human did not evolve from apes as many people think. There common ancestor    probably lived 6 million to 30 million years ago. Humans are classified as primates along with apes and monkeys. People walk on two legs which makes them hominids. Humans can walk up right because their pelvis is vertical unlike an apes which is tilted. Also humans spines are straight and come out of the bottom of their skull. Apes spines are curved and come out of the back of their skulls Scientists have discovered at least 18 different types of hominids. When an animal is classified as a hominid it must have some of the same characteristics as modern humans. Australopithecines were similar to apes but had a slightly larger brain, might have used stone tools and walked on two feet but still did climb trees. Most were probably vegetarian. They had slender bodies and human like jaws and teeth but had an ape like skull.   As early as 30,000 years ago two types of hominids were alive, called Neanderthals and modern humans. Both had the largest brains and were the more advanced at tool making than any other hominids. They both made clothes and art. Neanderthals might have lived 230,000 years ago and became extinct 30,000 years ago. Scientists do   not know what might have caused the extinction of Neanderthals.  A human’s scientific name is Homo sapiens. Humans have only been around since about 160,000 years ago. Humans originally lived in Africa and were believed to have left Africa 40,000 to 100,000 years ago. Humans are the only known living hominid. We are commonly compared to Neanderthals. Humans have a flatter face but a more round skull than Neanderthals, plus our tools were made differently. Humans were also smaller. Humans made art like sculptures, paintings, and carvings. Human evolution used to be believed to have come straight from primates to humans but now there is evidence to show many different human like creatures that once lived.
