Brain size and IQ

An interesting thing we seem to see in bats is that early auditory
processing has not expanded to the degree that would be expected if
echolocation was substituting for vision. It's much different than
prestriate visual processing, with much less of the afference seeming to
come through to the cortex. Yet bats maneuver acrobatically in auditory
scenes fully as complex as the visual scenes we handle. That suggests
nature is much more creative at solving these problems than we usually
give her credit for.
