Biological evolution has resolutely chosen to hand down genetic information through the fragile and uncertain process of sexual reproduction—employed by approximately 95 percent of the Earth’s species—rather than through the simpler and surer method of asexual reproduction. Drawing on the work of evolutionary biologists from America and abroad, this program examines four billion years of history to find an answer to the question of why sex has evolved into the primary mode of procreation.
