What Darwin Never Knew - PBS DVD

NOVA explores scientific evidence from DNA that supports Darwin's theory of evolution. How the staggering variety of animals may have resulted - 1.4 million different species - and how some evolved over time is noted. Comparison in embryonic development and genetic switches and genes are some of the processes discussed. "What actually drives evolution and turns one species into another?" is considered. NOVA shows how scientists are starting to "crack natures biggest secrets" via experimentation on numerous species. The results of this mountain of scientific evidence continue to confirm Darwin's theory by revealing clues in the diversity of life.
