Nothing explains why someone that lives in an environment where directional hearing would be beneficial lost this ability, so that they could solve algebra.
Natural selection. Maybe the ones with the ability to move their ears were more primative and less smart. When it came time to fight for breeding rights the ones who picked up a rock or stick and beat that ass got the woman. Or if the females had a choice maybe they preferred the ones without the weird ears.
There are random mutations in many different species. A little bit of radiation from the sun can change DNA. If the mutation is beneficial there is a better chance it gets passed on. Or maybe it could be a weird mutation that serves no purpose but it gets passed on anyway.
