What evidence did Charles Darwin use to support his theory of natural selection?
The finches that live on the Galapagos Islands off the South American continent in the Pacific. These finches became very specialized according the what kind of food they ate. If they drank nectar from long-throated trumpet flowers their beaks became very long and curved – an exact replica of the flower’s anatomy. If they ate hard seeds the finches developed a tough and thick crushing beak. There were 13 species of finches deposited over the islands developed from 1 common ancestor and each one had adapted to their different food supply. Also these birds developed all these different food supplies so they did not compete with each other over scant resources. It remains to be very fascinating. A piece of Darwin trivia: his main ship was called “The HMS Beagle/” The old Time-Life Nature Series books from the 1960’s had one book named “Evolution” where there is a whole chapter on this. It shows the drawings Darwin made of the finches and has photos of the birds themselves. There is a diag
