Thousands of miles from Wisconsin, a Senegalese female climbed up a savannah tree and prepared herself for a hunt. Swiftly, she chose her weaponâ??transforming a nearby tree branch into a sturdy spear. With great force, she jabbed the wooden spear into the hollow spaces of the tree, hoping to immobilize potential prey. While the huntress failed to land many successful kills, her actions have captured the attention of scientists around the worldâ??the Senegalese huntress is not a woman, but rather one of our close cousins, the female chimpanzee.
