This document outlines the theory of evolution and lists some of the early human groups according to that theory. It begins by stating that the theory of evolution is not based on religious texts but rather uses evidence from science. It then lists 3 early groups of humans - Australopithecines, Homo habilis, and Homo erectus - and describes Homo sapiens as the most advanced early humans who lived around 50,000-70,000 BC. Examples of specific early humans are also provided.
