There are both toads and spiders who deliberately roll downhill,
using their whole body as a wheel. Nature has not evolved separate
wheels because the same basic body plan with four limbs and twenty
tips has served to fill all available ecological niches, and there
were no full-rotation bearings even in the Burgess Shale selection of
body types. Now, can we please get back to the regular hot air stuff?

Dear List,
I am neither an engineer nor a physicist, but a biologist. I made the
observation that nature did not evolve wheeled locomotion because a
smooth road was a prerequisite for wheeled transport. Even humans,
who developed wheeled transport, use it only on roads or rails and not
elsewhere. .
