Harrison, author and journalist, armed with decades of research by social and biological scientists, makes the case that there really is no such thing as race, that manner of categorizing human beings based on superficial characteristics. Biological diversity does of course exist, but the author argues that contemporary science has determined that diversity does not mean there are different races. And, since the concept of race is an artificial if commonly accepted construct, it may be easier than most people think to eliminate racism. As the author says, "Nature did not rip us apart. We did, in our minds." Annotation ©2010 Book News, Inc., Portland, OR (booknews.com)
