Humans and the African apes all lack external tails. Monkeys, on the other hand, do have tails, which are useful for gripping trees and objects. Tails disappeared from apes 15–20 million years ago. Apes shin up and down trees rather than walking along branches as monkeys do. The earliest hominins climbed trees and walked on the ground. Fossil evidence shows how early humans made a gradual transition from climbing trees to walking upright on a regular basis.
