Darwin, Breeding and Barnacles 

Following the Beagle voyage, Darwin settled down to a quiet married life, relying on correspondence to gather facts.
He wrote thousands of letters as he gathered facts to support his still-secret theory.
Long before anyone had heard of evolution, Darwin produced four enormous books on barnacles, which helped establish his credentials (even his most committed opponents acknowledged that he couldn’t be ignored). And the books were also Darwin’s attempts to answer some complex questions about sex that will recur throughout the lectures.
