Episode 197: Carl Sagan on Natural and Artificial Selection

May 8, 2009

Carl Sagan’s Cosmos is still relevant, still enlightening, and still entertaining after twenty-nine (!) years. I am fond of them all, but the one that sticks in my mind is the tale of the Heiki Crabs, which bear, ostensibly, miraculous markings on their shells. Carl explains why, and relates this artificially selected phenomenon with the theory of natural selection.
