Can't Jump Like Normal Rabbits?

There is a species of rabbit that can't hop. So if it wants to go fast, it walks on its hands with its legs in the air. A team at upsela university in sweden have worked out what makes them unable to hop like normal rabbits. It's kind of a genetic problem they've got, isn't it? Do they get preyed on more, i wonder, because, wellhe they can't go that fast. Maybe they tend to not live in the wild very much.
