A gene defect may make rabbits do handstands instead of hop
One defective gene might turn some bunnies’ hops into handstands, a new study suggests. To move quickly, a breed of domesticated rabbit called sauteur d’Alfort sends its back legs sky high and walks on its front paws. That strange gait may be the result of a gene tied to limb movement. Sauteur d’Alfort rabbits aren’t the only animal to adopt an odd scamper if there’s a mutation to this gene, known as RORB. Mice with a mutation to the gene also do handstands if they start to run.
