Origin of Ardipithecus ramidus
Ardipithecus + New Latin ramidus, equivalent to Afar ramid “root” (from the closeness of this species to the roots of humanity) + -us adjective suffix; coined by U.S. paleoanthropologist Tim White (born 1950) and his colleagues in 1994. At the time of this discovery, the genus Australopithecus was well established, and White coined the genus name Ardipithecus to distinguish the new genus from Australopithecus
