Videos of a silverback gorilla walking upright like a man is currently becoming a smash hit on the internet/youtube.. The male, called Ambam, is part of a group of endangered Western lowland gorillas at Port Lympne Wild Animal Park, Kent (UK).
Ambam's father already used to display the same behaviour if he had handfuls of food to carry, one of the zoo's keeper told the media. Even his sister and half-sister are sometimes showing the same behaviour. Evolultion par excellence?!)
