No, it wasn't because he fell off the tower.
Scientists suggest that Gigantopithecus - the largest ape to roam Earth and the closest Nature ever came to producing a real King Kong - died out 100,000 years ago because it failed to tuck into savannah grass after climate change hit its preferred diet of forest fruit.
This real life King Kong weighed five times as much as an adult man and probably stood 9 feet (3 m) tall, according to sketchy estimates.
