It seems evolution developed intelligence as a way to for organisms to react and move through 3D space. An advantage was gained by organisms who can "understand" and predict, but biology just reused the same hardware for location, moving and modeling the 3D word for more abstract processes like thinking and pattern recognition. So evolution came up with solutions for surviving on planet Earth, which isn't necessarily the same as general problem solving, even though there are significant overlaps. Just the $.02 of a layperson.
