While studying evolution, Charles Darwin used the Galapagos Islands has his observation ground. However, there was one particular observation he made that we don’t hear as much about. Darwin found that island animals were tamer than their mainland relatives. A study from a collaboration of universities has confirmed this observation. Island dwellers can be considered tamer thanks to a lack of predators. The team noted the average amount of time it takes for an animal to initiate a flight response once they are threatened. Island animals have diminished escape behavior because predators are more scarce, or even absent, there.
