Yes, of course. But, something is not right. Perhaps a defect in this ape’s hips? I would love to see an xray of the pelvis. There is a reason they don’t stand or walk like this, and it’s not just that they don’t want to.

We don't know that. It could be that the gorillas have agreed to "fake it" by knuckle walking when humans are around.

That way we'll never bother to see if they're smart enough to pay taxes on income!

This bunch are giving away the show. I see a bad end for them once the others find out!
