''Australopithecus afarensis'' (Latin: "Southern ape from Afar") is an extinct hominid that lived between 3.9 and 2.9 million years ago. ''A. afarensis'' was slenderly built, like the younger ''Australopithecus africanus''. ''A. afarensis'' is thought to be more closely related to the genus ''Homo'' (which includes the modern human species ''Homo sapiens''), whether as a direct ancestor or a close relative of an unknown ancestor, than any other known primate from the same time. The most famous fossil is the partial skeleton named Lucy (3.2 million years old) found by Donald Johanson and colleagues, who, in celebration of their find, repeatedly played the Beatles song ''Lucy in the Sky with Diamonds''.〔 Also ISBN 0-521-46786-1 (paperback).〕 ==Localities== ''Australopithecus afarensis'' fossils have only been discovered within Eastern Africa. Despite Laetoli being the type locality for ''A. afarensis'', the most extensive remains assigned to the species are found in Hadar, Afar Region of Ethiopia, including the above-mentioned "Lucy" partial skeleton and the "First Family" found at the AL 333 locality. Other localities bearing ''A. afarensis'' remains include Omo, Maka, Fejej, and Belohdelie in Ethiopia, and Koobi Fora and Lothagam in Kenya.
