Hosted by Dr. Robert Winston, Professor of Fertility Studies at London University, this lively four-part British documentary series tried to explain why we do what we do, and why we've been doing it for so many years. Using candid-camera films, computer graphics, and funny props, Winston demonstrated how humanity's instinctual urges are ancient in origin and have developed over centuries of civilization (or lack of same). Among the points made in the course of the series is the importance of taste and smell in the formation of likes, dislikes, and romantic relationships. Individual episodes were as "Born to Survive," "Deepest Desires," "The Will to Win," and "Natural Born Heroes." In America, Human Instinct was seen in two installments over cable's TLC network on December 16 and 17, 2002.
