The Short Answer

The wildlife of the Galapagos islands often show no fear of humans at all. They have experienced little or nothing in the way of human predation. That is some pretty strong evidence. People talk all of this nonsense "The Great White Shark is the perfect predator." Not one Rocky Mountain Big Horned Sheep, Elephant, Rhino, Lion, Tiger, Bear, etc, etc, has ever been killed by a Great White Shark but humans kill them all the time. Humans are by far the single most dangerous predator that has ever lived. A *Tyranosaurus rex* wouldn't stand a chance against a human with a bazooka.
