This program is part of a PBS series that explores the nature of sex in all species, from plants to humans. In this first episode, the topic is the primal instinct for procreation. The documentary catalogues many permutations of the sex drive, from the mating dance of bird species, to the rutting drama of elk. Behind each expression, sometimes poignant or humorous, is the primal instinct to mate and produce offspring. Outstanding wildlife photography and scientific commentary provide the viewer a detailed look at this basic instinct.
