Many people out there don’t believe in evolution, they find it hard to believe that humans evolved from monkeys, or that they both evolved from a common ancestor. If you are one of those people, maybe this video might just change your mind. You know that gorillas don’t stand upright and that they don’t walk on two legs, but always with their legs and arms combined. This beautiful gorilla has spent so much time with humans that he decided to try to imitate them and start to walk like them. And he had taught himself how to do it! Incredible.
