Ambam (gorilla)

Ambam (14 April 1990 – 1 October 2022) was a male western lowland gorilla who gained notoriety in a 2011 viral video for walking upright at Port Lympne Wild Animal Park in Kent, England. Brief, occasional, and short spurts of bipedalism among primates is well known, but longer periods of sustained walking demonstrated by Ambam is considered rare by experts.

He is one of two famous gorillas, along with Louis, known for their unusual upright walking behavior. Scientists suggest that the ability of gorillas to walk upright for extended periods of time might be caused by their need to gather and carry food with their hands, a behavior also observed in chimpanzees, which could help explain the evolution of bipedalism in humans.
