In Cambridge, the sceptics were not impressed. To find additional supporting evidence of the antiquity of Reck's Olduvai Man, Leakey returned to Africa, excavating at Kanam and Kanjera. He easily found more fossils, which he named Homo kanamensis (Now considered a synonym of Homo sapiens[4]). While he was gone, the opposition worked up some "evidence" of the intrusion of Olduvai Man into an earlier layer, evidence that seemed convincing at the time, but is missing and unverifiable now. On his return, Leakey's finds were carefully examined by a committee of 26 scientists and were tentatively accepted as valid.[citation needed][5]
