Your Friday Monkey Dacker Feces Flingers

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...

Surprisingly, they found that chimps that both threw more and were more likely to hit their targets showed heightened development in the motor cortex, and more connections between it and the Broca’s area, which they say is an important part of speech in humans. The better chimp throwers, in other words, had more highly developed left brain hemispheres, which is also, non-coincidently, where speech processing occurs in people.
Such findings led the term to suggest that the ability to throw is, or was, a precursor to speech development in human beings.

After making their discovery regarding the parts of the brain that appear to be involved in better throwing in chimps, the team tested the chimps and found that those that could throw better also appeared to be better communicators within their group, giving credence to their idea that speech and throwing are related.
 That explains internet message boards.
