When it comes to jumping (and carrying babies) kangaroos are oddballs.
They don’t adjust their posture to be more upright, a technique most animals use to reduce muscular demands. Instead, roos keep their forward hunch, a baffling position since physics would suggest they’d suffer muscular or skeletal damage while accelerating that way.
To find out why this is not the case, researchers went to Alma Park Zoo in Brisbane, Australia, and set up an experiment to capture kangaroo motion with infrared cameras.
