Timeline of human evolution
The timeline of human evolution outlines the major events in the development of humans species and the evolution of human's ancestors. It begins with the time of the origin of life and presents a possible line of descendants that led to humans. This timeline is based on studies from paleontology, developmental biology, morphology and from anatomical and genetic data. The study of human evolution is a major component of anthropology. The Wikipedia timeline begins at 4000 MYA with the appearance of the ealiest life-forms and includes 10 MYA for when human ancestors speciate from the ancestors of the gorillas. The first anatomically modern humans (Homo sapiens) appear in Africa some time before 100kYA -- they evolved from Homo heidelbergensis.
