Galapagos Tortoise

The Galapagos tortoise played a role in Darwin's development of the theory of evolution. He realized that the tortoises on different islands had developed differently in response to their environment, writing "animals on separate islands ought to become different if kept long enough apart with slightly differing circumstances. – Now Galapagos Tortoises, Mocking birds, Falkland Fox, Chiloe fox, – Inglish and Irish Hare."
The news reported yesterday that a species of Galapagos tortoise previously thought to be extinct is still alive. Biologists found genetic markers unique to that species in living tortoises that appear to be cross-breeds.
Here Kaptain Kobold depicts Darwin observing a tortoise.
