Thailand's King Kong, a victim of climate change and diet?

Gigantopithecus – Nature's best attempt at producing a King Kong – was king of the forest in Thailand and surrounding areas until climate change and a dislike of grass likely caused its extinction, scientists suggest.

Why the real King Kong became extinct?

PARIS, AFP – The largest ape to roam Earth died out 100,000 years ago because it failed to tuck into savannah grass after climate change hit its preferred diet of forest fruit, scientists suggest.

Gigantopithecus – the closest Nature ever came to producing a real King Kong – weighed five times as much as an adult man and probably stood three metres tall, according to sketchy estimates.

In its heyday a million years ago, it inhabited semi-tropical forests in southern China and mainland Southeast Asia.

Until now, though, almost nothing was known about the giant's anatomical shape or habits.It is often referred to by scientists as G blacki, although its colour is unknown.

The only fossil records are four partial lower jaws, and perhaps a thousand teeth – the first of which turned up in the 1930s in Hong Kong apothecaries where they were sold as "dragon's teeth."

The fossils came from Thailand, where the great ape lived, but it never has been clear exactly where and there is little other evidence of the animal's life in what is today Thailand.

These meagre remains "are clearly insufficient to say if the animal was bipedal or quadrupedal, and what would be its body proportions," said Herve Bocherens, a researcher at Tübingen University in Germany.

Its closest modern cousin is the orangutan, but whether Gigantopithecus had the same golden-red hue, or was black like a gorilla is unknown.

Another mystery: its diet. Was it a meat-eater or a vegetarian? Did it share a taste for bamboo with its neighbour the prehistoric giant panda?

Answering this riddle might also tell us why a monster that surely had little to fear from other fauna went extinct.

That's where the teeth had a story to tell.

Examining slight variations in carbon isotopes found in tooth enamel, Bocherens and an international team of scientists showed that the primordial King Kong lived only in the forest, was a strict vegetarian, and probably wasn't crazy about bamboo.

These narrow preferences did not pose a problem for Gigantopithecus until Earth was struck by a massive ice age during the Pleistocene Epoch, which stretched from about 2.6 million to 12,000 years ago.

That's when Nature, evolution – and perhaps a refusal to try new foods – conspired to doom the giant ape, Bocherens explained.

"Due to its size, Gigantopithecus presumably depended on a large amount of food," he said.

"When during the Pleistocene, more and more forested area turned into savannah landscapes, there was simply an insufficient food supply."

And yet, according to the study, other apes and early humans in Africa that had comparable dental gear were able to survive similar transitions by eating the leaves, grass and roots offered by their new environments.

But for some reason, Asia's giant ape – which was probably too heavy to climb trees, or swing in their branches – did not make the switch.
