Speedy elephants use a biomechanical trick to 'run' like Groucho

Researchers found that Asian elephants can move at speeds of up to 15 mph, with some individuals reaching 50% faster than previously recorded speeds. This gait, dubbed "Groucho running", meets the biomechanical definition of running, where the center of mass appears to bounce and the footfall pattern is different from walking.

Early mammals used pelvic bones to trot, study finds

Scientists discovered that early mammals used epipubic bones to stiffen their bodies during trotting steps, allowing for increased mobility and locomotor efficiency. This finding suggests that the development of these bones contributed significantly to the evolution of mammals.
