THE REAL EVE: Modern Man's Journey Out of Africa

Stephen Oppenheimer, , . Carroll & Graf, $25 (320pp) ISBN 978-0-7867-1192-5

"There was only one main Exodus of modern humans from Africa, and no more," writes medical doctor and researcher Oppenheimer (Eden in the East), taking on advocates of "multiregional" origins and those who believe there were several exoduses out of Africa. Oppenheimer deftly brings together recent advances in population genetics, climatology and archeology to advance his theory that when groups of Homo sapiens left Africa approximately 80,000 years ago, they first headed east along the Indian Ocean, where they formed settlements as far away as India over several thousands of years. It was only during a respite in glacial activity, when deserts turned into traversable grasslands, that our ancestors headed northwest into the Russian steppes and on into eastern Europe, as well as northeast through China and over the now submerged continent of Beringia (located where the Bering Strait is today) into North America. Much of Oppenheimer's theory relies on recent advances in studies of mitochondrial DNA, inherited through the maternal line, and Y chromosomes, inherited by males from their fathers. The author devotes a chapter to the question of when humans first arrived in the New World, the raging Clovis vs. pre-Clovis controversy. Oppenheimer briefly discusses development of racial characteristics like facial structure and skin coloration, important topics often viewed as too hot to handle. This book will appeal mainly to science buffs; the level of detail may prove daunting to general readers. It is the basis for a three-hour special that aired earlier this month on the Discovery Channel. Illus. not seen by PW. (Aug.)
