Chemist Willard Libby. This was followed by the invention of the potassium-argon method. Both gave scientists techniques by which they could accurately determine the age of the strata in which fossilized bones were found, and sometimes the age of the bones themselves. Using these new tools, they have determined that Java man and Peking man, now classified as Homo erectus, walked the earth more than 500,000 years...
Young Leakey's self-confidence was justified; the Turkana region has proved to be an anthropological mother lode. In a basin several kilometers deep, walls of strata lie exposed, many-layered sandwiches of volcanic ash and ancient sediments containing the remains of complete prehistoric environments.

Then he began following his nose?with remarkable success. Turkana has yielded the richest accumulation of remnants of man and his predecessors...
