Neither chimpanzee nor human, Ardipithecus reveals the surprising
ancestry of both.
Abstract
Australopithecus fossils were regularly interpreted during the late
20th century in a framework that used living African apes, especially
chimpanzees, as proxies for the immediate ancestors of the human
clade. Such projection is now largely nullified by the discovery of
Ardipithecus. In the context of accumulating evidence from genetics,
developmental biology, anatomy, ecology, biogeography, and geology,
Ardipithecus alters perspectives on how our earliest hominid
ancestors—and our closest living relatives—evolved.
