Our cognitive reasoning portions of the brain are huge.  If we were to be dependent on directional hearing that would take up more brain power and take away from other abilities.

Over time the men who were smarter survived more often than they guys who depended on moving ears.

But the article suggested our brain still triggers us to move the ears. They just aren't there anymore. So by the article it has nothing to do with the limitations of the brain.
