The Science Guy takes on evolution in this episode of his award-winning series. Although many life forms have the same basic underlying characteristics, they don't look anything alike, because evolution has been at work for a long time. Bill Nye gets into genetic information, and explains how individual looks come from ancestors. Difficult science concepts undergo the Nye transformation, and emerge as coherent, easy-to-comprehend ideas, illustrated by off-the-wall antics, graphics, and many jokes.
