Neither chimpanzee nor human

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.
