King Kong Was Real - The Giant Ape Went Extinct 100,000 Years Ago, Due To Its Inability to Adapt

“Unfortunately, there are very few fossil finds of Gigantopithecus – only a few large teeth and bones from the lower mandible are known,” explains Prof. Dr. Hervé Bocherens of the Senckenberg Center for Human Evolution and Palaeoenvironment (HEP) at the University of Tübingen, and he continues, “But now, we were able to shed a little light on the obscure history of this primate.”

Together with his colleagues from the Senckenberg Research Institute, Prof. Dr. Friedmann Schrenk and PD Dr. Ottmar Kullmer, as well as other international scientists, the biogeologist from Tübingen examined the fossil giant ape’s tooth enamel in order to make inferences on its diet and to define potential factors for its extinction. “Our results indicate that the large primates only lived in the forest and obtained their food from this habitat,” explains Bocherens, and he adds, “Gigantopithecus was an exclusive vegetarian, but it did not specialize on bamboo.”

The team of researchers studied stable carbon isotopes in the tooth enamel of the large primates – which are able to reveal information about the animals’ dietary habits even after several million years. The examined teeth came from China and Thailand – among them the first record of Gigantopithecus, which was discovered by paleoanthropologist Gustav Heinrich Ralph von Koenigswald in 1935 among a collection of fossils from a Chinese pharmacy. The results show that the giant ape’s habitat was restricted to forested areas – even though the ape was presumably too heavy to climb trees. This was the case both in China and Thailand, where open savannas would have been available in addition to the wooded landscapes.

“In order to be able to comprehend the evolutionary history of primates, it is important to take a look at their diet,” explains Bocherens, and he adds, “Our results also contribute to a better understanding of the reasons that led to the giant ape’s extinction.”

Bocherens and his colleagues work on the assumption that Gigantopithecus’s size, in connection with its restriction to one habitat type, doomed the giant apes. “Relatives of the giant ape, such as the recent orangutan, have been able to survive despite their specialization on a certain habitat. However, orangutans have a slow metabolism and are able to survive on limited food.

Due to its size,Gigantopithecus presumably depended on a large amount of food. When during the Pleistocene era more and more forested areas turned into savanna landscapes, there was simply an insufficient food supply for the giant ape,” concludes the scientist from Tübingen.
