Reply to comment by Marsdreamer in What are more accepted hypotheses that similarly explain the aspects of hominid evolution that the "pseudoscientific" aquatic ape theory does? by KEVLAR60442
This is believed to be the reason no species ever developed wheels despite them being incredibly efficient. It's simply too large an evolutionary jump.

Aye, might not be a wheel, exactly, but there's at least one insect with interlocking gears in their legs that help them jump. a planthopper! https://www.livescience.com/39577-insects-with-leg-gears-discovered.html

How useful would wheels be without roads?

Also, sorry for the amateurish questions, wouldn't that require a rotating axle which is kinda impossible to develop? Like, everything is connected to the rest of the body. Maybe some weird symbiosis could do it? :)

Well, at least on the microscopic scale rotating joints are a thing, some bacteria and archaea have rotating flagella. See https://en.wikipedia.org/wiki/Flagellum
