The timeline of human evolution outlines the major events in the development of human species, and the evolution of humans' ancestors. It includes a brief explanation of some animals, species or genera, which are possible ancestors of Homo sapiens.
It does not address the origin of life, which is addressed by abiogenesis, but 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.

Famous quotes containing the words human and/or evolution:
“... women of the North, I ask you to rise up with earnest, honest purpose, and go forward in the way of right, fearlessly, as independent human beings, responsible to God alone for the discharge of every duty, for the faithful use of every gift, the good Father has given you. Forget conventionalisms; forget what the world will say, whether you are in your place or out of your place; think your best thoughts, speak your best words, do your best works, looking to your own conscience for approval.”
—Susan B. Anthony (1820–1906)
“As a natural process, of the same character as the development of a tree from its seed, or of a fowl from its egg, evolution excludes creation and all other kinds of supernatural intervention.”
—Thomas Henry Huxley (1825–95)
