Genetic Anthropology

Scientists' understanding of life is progressing more rapidly than at any point in human history, from the extraordinary decoding of DNA to the controversial emergence of biotechnology. Featuring pioneering biologists, geneticists, physicists, and science writers, Life explains just how far we've come - and takes a brilliantly educated guess at where we're heading.

When you think of evolution, the picture that most likely comes to mind is a straight-forward progression, the iconic illustration of a primate morphing into a proud, upright human being. But in reality, random events have played huge roles in determining the evolutionary histories of everything from lions to lobsters to humans. However, random genetic novelties are most likely to become fixed in small populations. It is mathematically unlikely that this will happen in large ones.

Race has provided the rationale and excuse for some of the worst atrocities in human history. Yet, according to many biologists, physical anthropologists, and geneticists, there is no valid scientific justification for the concept of race. To be more precise, although there is clearly some physical basis for the variations that underlie perceptions of race, clear boundaries among "races" remain highly elusive from a purely biological standpoint.

A new gene editing technology, invented just seven years ago, has turned humanity into gods. Enabling us to manipulate the genes in virtually any organism with exquisite precision, CRISPR has given scientists a degree of control that was undreamt of even in science fiction. But CRISPR is just the latest, giant leap in a long journey to master genetics. The Genetic Age shows the astonishing, world-changing potential of the new genetics and the possible threats it poses, sifting between fantasy and the reality when it comes to both benefits and dangers.
