When Charles Darwin was off observing wildlife in the Galápagos Islands, he wasn’t just looking at finches. In fact, one of the most striking creatures that Darwin found was the Marine Iguana (Amblyrhynchus cristatus). To Darwin, this species was strikingly…stupid.
Marine Iguanas are necessarily dumb, but when Darwin and his fellow shipmates reached the Galápagos, the iguana species was so far removed from human contact that it didn’t consider them a threat. One of my favorite Darwin anecdotes is about the famed naturalist repeatedly throwing a single iguana into the ocean, only to have it swim right back to rest in the same place.
These are huge, huge lizards, reaching over a meter in length, so the idea of one being tossed into the sea is a bit of a strange one. It really does make one wonder what other animal species might be like without the constant threat of predation or disturbance.
