In this video that compares artificial selection to natural selection, Carl Sagan gets to use his favorite word "billions", except ...

... except he's talking about the number of years natural selection has been working, instead of the number of stars in a galaxy.

Carl Sagan explains evolution.


  1. Excellent video! Thanks for posting it :-D

  2. LadyAtheist, thanks for watching it. I remember Carl Sagan's Cosmos TV series and his billions and billions of stars. Best science on TV ever, best music ever.
