It's likely that humans beat basically every other animal at this - because humans are social tool users. Most animals learn their body plan once and almost never change it. Humans have to learn to use new tools or work with other humans all the time.

Which seems to reuse the same brain wiring as what's used for controlling the body. To a professional backhoe operator, the arm of the backhoe is, in a very real way, his arm.

Curiously enough, most current neural interfaces don't seem to expose much of this flexibility. It's likely that you'd have to wire into premotor cortex for that - but for now, we're mostly using the primary motor cortex instead, because it's much better understood. The signals found there are more human-comprehensible and more prior work was done on translating them into useful motions.
