Our Oldest Ancestor
Our Oldest Ancestor? In 2000, a fossil finder from the Tugen Hills, Kiptalam Cheboi, uncovered a strange specimen of the little known species Orrorin tugenensis. At about 6.2-5.6 million years old, O. tugenensis, or the “Millennium Man,” is in the running to be the earliest of our ancestors to walk on two feet. Surprisingly, this Kenyan discovery seems to be an even closer relative of ours than world-famous, 3 million year old Lucy.
