Earth's largest ever ape died out because it refused to eat its greens – study

Gigantopithecus, which roamed the Earth 100,000 years ago, failed to adapt when climate change affected its favoured diet of fruit

The largest ape to roam Earth died out 100,000 years ago because it failed to adapt to eating savannah grass after climate change affected its preferred diet of forest fruit.

Gigantopithecus - the closest nature ever came to producing a real King Kong - weighed five times as much as an adult man and probably stood 3m (9ft) tall, according to rough estimates.
