Throughout the realms of living beings—in bananas and humans, in jungles and zoos, in test tubes and ocean depths—survival depends on adaptation, and adaptation on variation. And variation is the product of sexual reproduction. Through twelve half-hours of fascinating photography, the viewer observes in how many ways beings of all kinds reproduce: how male and female find one another, attract one another, couple, and produce one or more of a new generation that is alike but not identical; and how anatomical, behavioral, and social characteristics of a species are linked to the genetic goal of reproduction. 12-part series, 19-28 minutes each.
