Reply to comment by xDaBaDee in I saw in a video that chimpanzees and gorillas do not knuckle-walk in the same way, but they didn't explain what the difference is. Could someone elaborate on the physiological/anatomical differences? by [deleted]

I was really surprised to find that moment of suspension wasn't when the legs were all outstretched, but when they were gathered under the horse, just before the hind legs touch down.

Some dogs have a double suspension gallop which is more what Iwas expecting. All four legs are off the ground when gathered under them, and again when they're all stretched out.

The dogs that run like this have much more flexible spines than horses, and are also much lighter for their height. A horse doesn't have enough flexibility and power to run like that.
