A three-year study of seventeen wild chimpanzees living in Gombe National Park, Tanzania, found that the majority used their left hands when fishing for termites with sticks. Twelve of the animals used the left hand, four used the right hand, and one was ambiguous. The research was reported by the Yerkes National Primate Research Center at Emory University in Atlanta. Some previous studies have also indicated a left-handed preference among chimps using sticks, but some suggested a right-handed preference when cracking nuts.
