A German research institute has recently discovered why the biggest primate species to ever walk the earth went extinct.

The Gigantopithecus, who were ten feet tall on average and weighing over 1,100 pounds, were large apes who lived in southeast Asia deep within its jungles from approximately nine million to 100,000 years ago. They are often described as the real-life King Kong, and vanished from their habitats with little left behind. The majority of fossils found of Gigantopithecus are jawbones. Scientist analyzed the individual teeth using carbon isotopes and were able to uncover that King Kong was an extremely picky eater. Their diet consisted of a very specific selection of fruits, vegetables and nuts and did not eat bamboo. Around the time of their extinction, an ice age was advancing, turning their jungle homes into savannas. Thier homes shrunk as well as those specific foods, and refused to adapt their eating habits to the leafy, grassier choices. The

Gigantopithecus did not have a sufficient food supply and therefore died out. Some scientists believe that some crossed over the Beringian land bridge into North America during that Ice Age and are responsible for modern-day Bigfoot sightings. As far as we know, King Kong is now only fiction because he refused to eat more vegetables.
