Ardi’s skeleton, which is more than 50 percent complete, dates to about 4.4 mya.Fossils found since the early 1990s have begun to hint at just how complex the hominin bush was in the three million years or so following the time of , both known from South and East African sites.This early radiation (diversification) of hominins, of which the latest survivors lived as recently as about 1.5 mya, made for a rather motley assortment.These are thought to belong to the same species as the remarkably complete 1.6-million-year-old skeleton named “Turkana Boy,” found at nearby Nariokotome.The nature of the association between the two finds is not yet completely evident, as even partial hominin skeletons are almost vanishingly rare as researchers delve deeper into the past to a time before the introduction of burial practices.
