Human evolution
People have known for centuries that man and the apes are related. Clearly, even though they look different, their anatomy is similar. For this reason, during the 18th century, Buffon and Linnaeus put men and apes together in a single family. In the 19th century, Charles Darwin suggested that animals have very similar anatomies when they share a common ancestor. In fact, humans and apes are close relatives. Both are primates: the order of mammals which includes monkeys, apes, lemurs and tarsiers.
