Giant teeth on a fossil palate represent the first trace of the earliest known man, who lived in East Africa more than 600 thousand years ago, according to present thinking of most anthropologists. Oldest tool-maker yet discovered,Zinjanthropus boisei adds a link in the chain of human ancestry, the author believes. The broken palate, justas it was uncovered in Olduvai Gorge, appears here not quite life size. Molars are nearly twice the width of modern man's. The author, a noted British archeolo gist, is curator of the Coryndon Museum in Nairobi, Kenya. His search for ancient remains continues under a National Geographic Society grant.
