Great Transformations
- 2001 ----- color ----- 56 min ----- vhs
- (Evolution series, Part 2) What triggered the incredible diversity of life on earth? How have complex life forms, including humans, evolved? Is there direction to evolution? Was human intelligence inevitable? Focuses on some of evolution's most important changes--among them the development of the four-limbed body plan, the journey of animal life from water to land, the return of mammals to the sea, and the emergence of humans. Driven by a combination of opportunism and a genetic "toolkit," these great transformations define the arc of evolution. And they suggest that every living creature on earth today, and every species that has ever existed, is a variation on a grand genetic theme--a member of one, and only one, tree of life (Closed-Captioned).
