Study Notes

Human Evolution

  • All humans belong to the species Homo sapiens, which evolved from a common ancestor in the Homo genus.
  • Hominids, an ancestral group to humans, are characterized by bipedalism (walking upright on two feet).
  • The earliest known hominid fossil, dated at 4.4 million years old, was discovered in Aramis, Ethiopia.
  • A subsequent fossil, Australopithecus afarensis, was followed by "Lucy", an almost complete Australopithecus skeleton found in Ethiopia, dated to around 3.2 million years old.

Genus Homo

  • The genus Homo includes three distinct species: Homo habilis, Homo erectus, and Homo sapiens.
  • Homo habilis, considered the oldest Homo species, had a nickname "handy human" due to the tools they used.
  • Homo habilis fossils were found in the Omo Valley, Ethiopia.
  • Homo erectus, meaning "upright human", emerged approximately 2 million years ago.
  • Homo erectus developed larger and more diverse tools than their predecessors.
  • Homo erectus were the first hominids to migrate out of Africa to Europe and Asia, facilitated by their ability to control fire.
  • Homo erectus fossils have been found in the Omo Basin, Melka-Kunture, Konso–Gardula, and Middle Awash, Ethiopia.
