Why did the Gigantopithecus go extinct?

We may now understand why orangutans survived and are still with us while Gigantopithecus Blacki went extinct.

They may have weighed 200–300 kg/440–660 lbs. and reached a height of 3 meters/10 feet, making them the largest primates to have ever lived. We don’t know much about them other than the fact that they are related to the above-mentioned orangutans. All we discovered was their mandibles and teeth. These provided us with hints regarding their diet: they were herbivores, consuming several abrasive vegetable items such as stems, bark, twigs, dirty tubers, and roots, as well as fruits from the fig family and other fruits.

Between 2 million and 250,000 years ago, they were present in Southeast Asia, and we believed that climate change may have caused their extinction, and maybe because of pressure from early humans. We now know that about 330,000 years ago, their range drastically decreased. When their remains were discovered, researchers dated and reexamined the sediments. Gigantopithecus Blacki went extinct between 295,000 and 215,000 years ago, it turns out.

From 600–700,000 years ago, when the temperature changed and caused the habitat to which they were well adapted to shrink, it became harder for this enormous ape to live. These were mostly dense forests interspersed with grasslands. Fruits became harder to get by…
