Answer:
Human Evolution
Evolution has created a huge biodiversity. Natural selection, genetic drift, and speciation – all these factors shaped the biodiversity. The new species have never left a choice to mate with the previous ones. Each species had to reproduce in their own way with their own group members. This leads to the branching of species i.e., a common ancestor diverges into two or more different lineages. Human evolution also has the same story. If we talk about human evolution, the first thing which comes to mind is a chimpanzee. Even though human evolution is not from chimpanzees, they share a common ancestor. Both the species of human and chimpanzee evolved in their own way from a common ancestor as per their living conditions.
Nowadays, we can trace the evolutionary relationships between species easily by using fossils, DNA sequences, and palaeontological excavation, etc. It is said that human evolution began in Africa. The earliest genus of Homo to be ever discovered is Homo habilis, which lived nearly 1.75 million years ago. The next major step in evolution was when our ancestors, Homo erectus stepped out of Africa and migrated to other parts of the world. They mingled with the new and the old ones to produce a diversity of human species. We find different races of people around us, but all of them emerged from a universal common ancestor of all primates
