In a paper published Thursday in the journal Science, Lordkipanidze and colleagues say that skull and four other fossil craniums recovered at the site contain features previously ascribed to three different species of human ancestor: Homo habilis, Homo rudolfensis and Homo erectus.
The explanation for this is clear, they say: All three species must be one and the same. Differences once perceived to be the mark of separate species are in fact the result of normal variation in physical features, age and gender, they say.
