The Omo remains are a collection of hominid bones discovered between 1967 and 1974 at the Kibish sites near the Omo River, Omo National Park in south-western Ethiopia. The bones were recovered by a scientific team from the Kenya National Museums directed by Richard Leakey and others. The remains from the Kamoya's Hominid Site (KHS) were called Omo 1 and those from Paul's Hominid Site (PHS) Omo 2. Parts of the fossils are the earliest classified by Richard Leakey as Homo sapiens. The results of 40Ar/39Ar dating of the geologic tuffs in 2004 were for the layer below the fossil tuff (Member I - 198 ± 14 ka) and the layer over the fossil tuff (Member III - 104 ± 7 ka). In a 2005 "Nature News" article on the fossils, Nature magazine called Ethiopia the current choice for the "cradle of Homo sapiens."
