Individual habiline specimens such as H. rudolfensis (er 1470) and H.
habilis (er 1813) are separated by ~20,000 yrs in some sediments.
Arguing that one is "older" than the other is not really supportable at
this point, unless you want to assume that the Omo teeth or the Chemeron
(?) fragment belong to H. rudolfensis rather than H. habilis.
