Evolution has also shaped the perfect endurance runner, capable of traversing vast home ranges and chasing down prey with speed and incredible stamina. A new first-of-its-kind study of painted dog anatomy has revealed a whole range of mechanisms that make this energetic lifestyle possible–showing how the design of the limb muscles, ligaments, and even bones allows these remarkable carnivores to resist fatigue, coordinate their movements, and propel their bodies forward over great distances. But of course, even the most proficient runners need a little collective rest now and again. #painteddogs #endangeredspecies #wilddogs」9月26日 15時40分
