In recent years it has becomm possible to use DNA to trace human development. For instance the people of iceland believed themselves to be of Viking descent. DNA testing has shown that yes, the men of Iceland are of Viking descent. But the women came from England and Scotland. Apparently the Vikings stopped off to capture a few women on their way west.

This little tidbit of knowledge is a mixture of multiple sciences and fields of study. The beliefs of the Icelanders has to come from a humanities perspective. The DNA evidence has to come from the hard science in the laboratory. (The supposition at the end is my own.)

Dr. Cavalli-Sforza, as the title of this book says, has spent a lifetime of study spanning across many fields of study in the hard sciences and in many different areas of the humanities. This is a book that spans the globe from his offices in California and Italy to field studies in Africa and elsewhere.

Written by an anthropologist and a geneticist, this book is also a good combination of crossing the fields of science and humanity.
