"The first segment in a six part series examining the natural history of sex. Part one looks at the remarkable variety of ways the sex urge is expressed among the Earth's countless species. Some species only need one sex while in others each member is both sexes at once, while still others have been reproducing for millennia with no sex at all. In some species, a female devours her suitor after having sex, in others a single female is attacked by a mob of males. A fascinating look at the incredibly diverse and sometimes strange ways of how life reproduces." . . . . . . . . . . . . "Reproduction humaine." . . "Comportement sexuel des animaux." . . . .
