Ardipithecus ramidus

After 15 years of excavation and analysis, the folks working in Middle Awash, Ethiopia have finally published the description and interpretation of the anatomy and functional morphology of Ardipithecus ramidus. The have a partially complete female skeleton as well as bits and pieces of other individuals. They interpret "Ardi" as a dietary generalist who walked upright (though not like we would) on the ground, moved much like Old World monkeys in the trees and was fairly sexually monomorphic.
