Evolution? Survival of the fittest, bollocks survival of the fattest more like. I have never in my life seen so many lazy animals on one island. Sealions asleep in the hotels, giant tortoises too tired to lift their head off the ground let alone put it away. Boobies, pelicans and herons in the fish market, in it. Now that's evolving to suit your environment. And Lonesome George most famousist of all tortoise's butt sticking out from a bush.
