(Feb.5, '15) The more scientists study pigeons, the more they learn how
their brains—no bigger than the tip of an index finger—operate in ways not so
different from our own.
In a new study from the University of Iowa, researchers
found that pigeons can categorize and name both natural and manmade objects—and
not just a few objects. These birds categorized 128 photographs into 16
categories, and they did so simultaneously.
