Human evolution is a long and complex process that began millions of years ago.
Some of the major milestones discussed in educational timelines include the development of bipedalism, changes in brain size, stone-tool technology, migration beyond Africa, controlled fire, language and symbolic culture.

A seven-stage framework can make the subject easier to understand by introducing important groups such as Australopithecus, Homo habilis, Homo erectus, Neanderthals and Homo sapiens.
However, these stages should be viewed as a simplified learning framework rather than a literal straight-line sequence.
The Campus Review provides a detailed human evolution study guide covering species, fossils and major milestones.
