According to their results recently published in the journal Royal Society Biology Letters , red kangaroos, when traveling at low speed, especially for their food (that is to say, most of the time), still retain not two but three ground support. To walk, they pose as alternately their front paws and tails and their two hind legs and tail. And in both cases, that is the tail end which provides the main pulse, so that the front legs, they do serve as support virtually.

"Kangaroos use their tails for support, propel and fuel their movement. Actually, they perform more mechanical work with it than we do with our legs," said Maxwell Donelan, University of Colorado Boulder ( United States ), one of the authors of the study. "Their tail has over twenty vertebrae that act as our feet, our calves and our thighs," he adds. Something to inspire the engineers who try to mimic nature to create ever more powerful robots. But the most extraordinary in all this, it may be that before their tail function takes fifth leg to current kangaroos scientists believe that the tail of their ancestors was prehensile and allowed them to cling to trees , as a third hand! Fascinating are the paths of evolution ...
