The document summarizes human evolution from approximately 1.2-4 million years ago to the present. Early humans like Australopithecus afarensis were apelike but began walking upright. Later groups such as Homo habilis made more advanced tools and Homo erectus hunted with tools. Homo sapiens neanderthalensis were skilled hunters while Homo sapiens cro-magnon were the first to bury their dead. Anatomically modern humans, Homo sapiens sapiens, emerged in Africa around 10,000 years ago and civilization began to develop.
