Why did the world’s biggest ape go extinct?

The largest primate to ever roam Earth went extinct because it could not adapt when its environment changed, reveals a detailed study of its teeth and the caves they were found in. Gigantopithecus blacki was around twice the height of a person and weighed up to 300 kilograms. Pollen analysis shows that around 700,000 years ago, the dense forests that it relied on gave way to more grassland. Trace elements in G. blacki’s teeth show that it was forced to consume a less nutritious, more fibrous diet.
