Chimps Sharpen, Use Spears to Hunt

In February of this year Jill Pruetz, an anthropologist with Iowa State University, witnessed Kenyan chimpanzees break off branches from trees, sharpen them using their teeth, and then use these spears to hunt lesser bush babies, a kind of small primate. The bush babies sleep in the hollows of trees, and the chimps were repeatedly seen jabbing their spears into the hollows and pulling them back out with fresh bush baby babies impaled on the end.

Pruetz recorded a video of the chimps using the tools.

The world’s most prominent scientists used to believe that the use of tools was an exclusively human trait. Man, were they way off. In the past two decades, numerous animals been witnessed using tools from their surroundings to aid in finding prey, making nests, and various other purposes.

Orac is the nom de blog of a humble surgeon/scientist who has an ego just big enough to delude himself that someone, somewhere might actually give a rodent's posterior about his copious verbal meanderings, but just barely small enough to admit to himself that few probably will. That surgeon is otherwise known as David Gorski.

That this particular surgeon has chosen his nom de blog based on a rather cranky and arrogant computer shaped like a clear box of blinking lights that he originally encountered when he became a fan of a 35 year old British SF television show whose special effects were renowned for their BBC/Doctor Who-style low budget look, but whose stories nonetheless resulted in some of the best, most innovative science fiction ever televised, should tell you nearly all that you need to know about Orac. (That, and the length of the preceding sentence.)

DISCLAIMER:: The various written meanderings here are the opinions of Orac and Orac alone, written on his own time. They should never be construed as representing the opinions of any other person or entity, especially Orac's cancer center, department of surgery, medical school, or university. Also note that Orac is nonpartisan; he is more than willing to criticize the statements of anyone, regardless of of political leanings, if that anyone advocates pseudoscience or quackery.
