Learn about Ardipithecus ramidus, a possible human ancestor from 4.4 to 4.2 million years ago, discovered in Ethiopia. Find out its features, distribution, relationships and fossil discoveries.
4-million-year-old fossils of Ardipithecus ramidus found in 1992 and named in 1994. The anatomy of Ar. ramidus is best understood by examining Ardi, the partial skeleton found at Aramis.
