Answer:
Many of the proteins produced by humans have identical or nearly identical counterparts in chimpanzees. For example, the hemoglobin in your blood is about 99% similar to chimp hemoglobin. This suggests that humans and chimps share a common ancestor, from which both species evolved via evolution.
Explanation:
Evolution can be described as a process by which organisms tend to change over a period of time and develop characteristics which allow them to adapt to the environment in a better way. The similarities in the genetic and functional characteristics in different organisms show that the organisms might have had a common ancestor in the past. Changes in the ancestors through evolution caused different organisms to be formed having genetic similarities.
