Was iOS evolved from the iPod OS ? a lot ? a little ?

No- iOS is a stripped down OSX. iPod classic os was not related to that. The Core Audio framework is what makes iOS low latency. It was developed after the iPod.

I have no idea of the internals of the iPod. As I understand it, iOS benefited immensely from the work already done on OsX. I don't even know whether they planned for it or just benefited from a mature module already in place.

IIRC the very first iPods actually had licensed much of the under the hood software.

I could be confusing them with Palm OS, which did the same for the kernel of their first Pilots...

iOS is just a rebranding of what used to be iPhone OS.
