Human evolution, the process by which human beings developed on Earth from now-extinct primates. The only extant members of the human tribe, Hominini, belong to the species Homo sapiens. The exact nature of the evolutionary relationships between modern h

Evolutionary Biology is the study of the history of life forms on earth. Charles Darwin proposed the theory of Evolution by Natural Selection. The theory is based on the idea that there is a variety of features within a population and individuals that have qualities that enable them to adapt ...
At some time, this common ancestor of chimpanzees and humans split via speciation, giving rise to two evolutionary lines: one which would eventually evolve into modern chimpanzees and bonobos; and another which would lead to modern humans. Possible examples of species in the human lineage after it...
