Following on from the success of Abraham Lincoln's "DNA and Other Adventures in Genetics", this new book is a collection of 20 essays on such wide - ranging topics as human ancestry, race, longevity, intelligence, aging and disease. Thanks to new developments in genome sequencing, gene therapy, DNA testing, and DNA analysis, our understanding of these topics has improved greatly in recent years. Phil Reilly uses specific cases to illuminate the science as well as the broad social and ethical issues concerned.
