Similarities Between Chimpanzees And Chimpanzees

Decent Essays

For years, there has been question as to where humans came from. Many people believe we evolved from monkeys, but that is not true. Human are more closely related to modern day apes. However, we did not evolve from apes either. In Africa, gorillas and chimpanzees are the two primates which humans share a common ancestor with. This common ancestor is said to have existed 5 to 8 million years ago. The species then divided into two separate lineages and evolved into gorillas and chimps, and the other into early ancestors called hominids. Fossils have been found that provide evidence of these hominids. It is hard for fossils to be categorized as species or another. Like every other creature, no two are alike so it’s hard to separate the hominid fossils because they have evolved and some changed into new species. The main evidence is that of fossils. In the deeper layers of the Earth 's crust we find no fossils. Then we find fossils of simple organisms in younger layers. As we go up higher in the rocks, we start finding larger, more complex organisms along with the simple ones. Sometimes we see fossils that look like a step between older fossils and newer ones. As we travel through time, or up layers of fossils, we also see some kinds of fossils disappear. These types of plants and animals probably went extinct. The first primates appeared in the fossil record about 70 million years ago. In rocks that are about 3 million years old, the first human-like fossil skeletons were
