Sometimes as individuals and sometimes in swarms that may run to millions; sometimes the male moves in relation to the female organ and sometimes she in relation to his; sometimes on the ground, at other times underwater or in mid-air...

This program shows the next step up in sexual coupling—the myriad ways in which animals from dragonfly to common toad find the appropriate environment, and male and female the appropriate sexual organs of one another, mate, and how each act of sexual reproduction leads to further diversity of the species.

Reproduction and Diversity

Sexual reproduction never produces the same result twice but rather ensures variation in the offspring of a species. This program follows the care and development of the egg-the relationship of the number laid, fertilized, and hatched to the survival...(more details)
 
Behavioral and Biological Differences

Behavioral and social differences between the sexes in humans may be cultural, but some at least are clearly linked to biology. Using as an example an African village where the roles of sexes are strictly defined, this program shows that, in humans, ...(more details)
