为什么蝙蝠挂颠倒了?

这有点像问,“为什么人们走路腿?”人could walk on their arms instead, and some people (acrobats for example) actually do it sometimes. But our legs are a lot stronger than our arms, and the whole human body is set up for walking with the legs. Walking with the legs is easy and comfortable and natural. So we usually walk with our legs rather than our arms.

它是相同的蝙蝠。蝙蝠的身体被设置为挂颠倒。事实上,如果你看一个蝙蝠的腿,他们是设置,不用做任何事,他们自然地抓住当蝙蝠是颠倒的。蝙蝠的重量穿上肌腱,脚关闭。所以蝙蝠挂颠倒了,因为它是简单和舒适和自然的蝙蝠。
