UNDATED PHOTO: (EDITORIAL USE ONLY) The July 11, 2002 cover of the journal Nature shows a skull believed to be the earliest member of the human family. The skull, which is thought to date back six or seven millions years was found last year by an international team of palaeoanthropologists working in Chad, Central Africa. The journal's palaenontology editor said that the discovery of this skull may rival the first ?ape-man? discovered 77 years ago. (Photo by Nature-M.P.F.T./Getty Images)
