In this concise and well-written work, Wells provides an accessible introduction to genetic anthropology, the study of human history using genetic evidence. Wells is the director of the Genographic Project, which collects DNA samples from a wide array of world populations to better understand human history over the last 200,000 years.
Wells does a fantastic job distilling both genetics and genetic anthropology into straightforward topics, presenting sophisticated material accessibly without oversimplification. He gives the reader the basic concepts (Y chromosomes, mtDNA, haplogroups, genetic markers) and then proceeds to step through genographic research from its 19th-century origins to the present day. In so doing, he takes the reader back to the 170,000-year-old female genetic ancestor of every person alive today: the so-called African Eve.
It is a remarkable journey that will appeal to readers of all backgrounds interested in exploring the science and research behind human evolution, although those with more experience in the sciences may find some of the material elementary.
