"RACE IN MIND: RACE, IQ, AND OTHER RACISMS

By Alexander Alland Jr. Palgrave MacMillan, 2002, 219 pp., $26.95 ISBN: 0-312-23838-X

Anthropologist Alexander Alland offers a comprehensive review of the recent history of research on race and IQ, offering critiques of the biological determinism of a number of theorists including Carlton Coon, William Shockley, Leonard Jeffries and others. He explains the basis of evolutionary genetics for the general reader and concludes that biologically, "race" cannot explain human variation.

Alland is the former chair of the anthropology department at Columbia University."
