Just as human beings evolved from the most useless apes, capable apes can climb trees, run and jump, and also have a high position in the group of apes. Only the most stupid and difficult to climb trees have to pick up the miscellaneous fruits on the ground and stand on the branches and leaves of Guangyejun to eat them. Climate change (ice age), those who have the ability to run to the tropical areas with many fruits and gain territory. number
So is the stupidest orangutan. Other orangutans can climb trees by themselves, the most stupid ones can't, just put things under their feet and finally evolved into scaffolding.
