A family of ethnic Kurds has been found in Turkey that are quadrupedal - they walk on hands and feet. Is it a genetic defect? Or is it a missing link to our forebears, who started walking on two feet more than 2 million year ago?
Scientists are still speculating the shift to bipedalism - one theory is that it was merely to be able carry back a larger amount of food - enabling the upright bloke to feed a whole family back home rather than just oneself. Eventually the hands developed further, leading to the multi-functional hands we have today which can bounce basketballs up and down like no Gorilla can. [source: National Geographic]
