No Heartbeat? Don't Worry!
Evolutionists say that an animal's unique features developed because the unique feature gives the animal some survival benefit. Just what that benefit might be is open to interpretation, and sometimes the explanation is a little fuzzy. Sometimes the explanation just doesn't work.
Such is the case with the marine iguanas of the Galapagos islands. These iguanas are excellent swimmers and search underwater for much of their food. However, when they are underwater they are vulnerable to the marine food chain. Sharks find the marine iguanas very tasty. With their sensitive hearing, these predators can hear the heartbeat of a hiding iguana 12 feet away. So part of the iguana's defense is to stop its heartbeat voluntarily. Amazingly, the iguana can keep its heart stopped for up to 45 minutes without suffering any ill effects.
Evolutionists explain that this ability evolved because it gives the iguana a survival advantage in shark-infested waters. Obviously, a creature's ability to stop its heart for this long requires some major internal modifications. To believe that the iguana knew all the changes it needed to intentionally stop its heart for 45 minutes without death requires quite a leap of faith! However, this evolutionary explanation just doesn't work. The Komodo dragon can also stop its heart. For the Komodo this ability provides no survival advantage, for these huge lizards have no natural enemies.
These lizards received their special abilities from their wise Creator. Their special abilities glorify Him, not mindless evolution.
