NEWS - GORILLA TIRES OF ALL FOURS, STARTS WALKING UPRIGHT ON TWO LEGS

Gorilla tires of all fours, starts walking upright on two legs

UNITED KINGDOM - A gorilla at a British Zoo has become an Internet sensation, all because he's given up "knuckle walking."

Gorillas, of course, normally get around on all fours. But Abram walks upright on two feet.
The gorilla keeper says it seems to run in the family. He says Ambam's father used get around the same way when his hands were full. 

We wanted to know how normal is it for gorillas to just stand up and start walking? And will the gorillas at the Denver Zoo start doing it? We asked the CEO of the Denver Zoo. 

"I think what it demonstrates to me is you can know a lot about animals but they are always going to come up with something really surprising," CEO Kyle Burks said. 

Zoo vets say the gorillas are doing fantastic, enjoyed Friday's warm weather, but they aren't showing any signs that they will start walking around like humans anytime soon.
