Carl Sagan Explains Evolution in the Original Cosmos


If you've been watching Neil deGrasse Tyson's Cosmos: A Spacetime Journey then you've seen the wonderfully animated segments on Evolution. It was touched upon in the first episode and discussed in much more detail in the second.

This video is the evolution segment from Carl Sagan's original Cosmos. The animation is much less complex and new information has come to light since the original series aired. It is, however, still interesting and it's Carl Sagan so it could never be bad.
