Researches find poop-throwing by chimps is a sign of intelligence
(PhysOrg.com) -- A lot of people who have gone to the zoo have become the targets of feces thrown by apes or monkeys, and left no doubt wondering about the so-called intellectual capacity of a beast that would resort to such foul play. Now however, researchers studying such behavior have come to the conclusion that throwing feces, or any object really, is actually a sign of high ordered behavior. Bill Hopkins of Emory University and his colleagues have been studying the whole process behind throwing and the impact it has on brain development, and have published their results in Philosophical Transactions of the Royal Society B.
