        NOVA: Judgment Day: Intelligent Design on Trial | Human Chromosome 2

        This video segment from NOVA: "Judgment Day: Intelligent Design on Trial" reveals how genetic evidence helped to confirm an important component of Darwin's theory of evolution by natural selection: the common ancestry of humans and apes. In particular, it explains that humans have one fewer chromosome pair in their cells than apes, due to a mutation found in chromosome number 2 that caused two chromosomes to fuse into one.

        This video is available in both English and Spanish audio, along with corresponding closed captions.
