Did you hear that humans used to be monkeys? Well, that’s not exactly true. The first humans known as hominids came from chimpanzees. Before that, the chimpanzees descended from the first primates who lived 45 million years ago. Humans share common ancestors with apes, but they are not actually related liked a grandparent and grandchild. Human evolution scientifically explains how we have been changing over the years. Scientists saw some important changes that allowed humans to evolve from our common ancestor. The first change was bipedalism. It means to walk upright and straight on two legs. This was a trait seen in the first group of humans. Hominids were the first human group that used bipedalism. They came out of the trees and started to walk like we do now. If you look at a monkey     They lean forward and don’t stand up straight. Instead of them walking like us they do something different they us knuckle walking they don’t walk on their hands but on their knuckles. Now if you look at us we walk  upright and don’t lean forward as much.   Scientists have collected evidence that the original humans shared one ancestral group called the hominids. The earliest Hominids, were known as Australopithecines, They were like apes however they are different too. Their brains were a little bigger, Australopithecines used tools made out of stone and they can climb trees and walk on the ground. There is a lot of evidence that proved that Australopithecines lived in different places in Africa. They are said to have lived 3 million years ago. At that time there were many other hominids that were living too. They all were different though. One had a human jaws and teeth but it had a small head. Another ate only vegetables and others ate meat. Others had huge bodies some had small bodies and were more ape like. 2.4 million years ago a new group of hominids appeared. They were similar to the Australopithecines, but they were more like humans then apes. This group was related to a group called Homo or newer humans. They had bigger heads and brains, they used better tools and their faces were more flat. This group of “new humans” lived on many different continents. They were also the first to start migrating and adapting to the surroundings. These migrations were probably for food because if everyone was in the same country and you only got food from that one place, that food will eventually run out so you will have to move. About 30,000 years ago Hominids started to live in the same areas. They both had bigger brains and advanced tools. They also had clothes and art. Scientists found evidence that we came from these Hominids. Awhile before these hominids, about 230,000 years ago lived Neanderthals. These Hominids lived in Europe and Asia. They were hunters and hunted big animals. They had fires and wore cloth. They also cared for there sick and buried there old. About 30,000 years ago they disappeared.
