Human Evolution

Human evolution is the process of evolution of humans from early man to anatomically modern humans. The process of evolution in humans leads to the gradual development of traits like bipedalism. Humans are the highly social animals that make them the most advanced animal on Earth.  Human evolution is an outcome of interaction among the following processes:
