Just 100 thousand years ago, the territory of modern Asia was inhabited by monstrous apes. This is not an exaggeration. Gigantopithecus reached a height of three meters and weighed up to half a ton. They had their own tools of labor and could well have developed into a separate type of intelligent creatures.
Modern archaeologists have already broken a dozen spears while discussing Gigantopithecus Blacki. Grover Krantz, a German scientist, put forward the theory that gigantopithecines were bipedal.
Although the remains of the skull of a gigantopithecus have not yet fallen into the hands of anthropologists, the size of the jaws suggests that the brain volume of these monkeys should have been noticeably larger than that of the gorilla. But the maximum brain size of a gorilla exceeds the minimum normal size of a human brain! Therefore, in Gigantopithecus, the average brain size should be approximately within the range of Pithecanthropus. This, of course, does not guarantee great intelligence (especially considering the grandiose body size), but size does matter! Moreover, sometimes huge stone tools are found in the same layers. It is inconvenient to hold them in your hand, and the size of the hand of Pithecanthropus and other ancient people was no larger, or even smaller than ours. Are these the tools of the Gigantopithecus? - Stanislav Drobyshevsky, anthropologist.
What caused the extinction of gigantopithecus is not known for certain until now. Are they even extinct? A number of anthropologists believe that these huge monkeys exist today. In principle, the theory is logical enough. Gigantopithecus did not have an incentive to develop mental abilities - they were more than enough in size and strength. They could well degrade and now live in separate enclaves in places that are hard to reach for humans.
