<i>Warlpiri number words are limited to one, two and many, the researchers said. Anindilyakwa has words for one, two, three which sometimes includes four and more than three.</i><p>I could have sworn I read that tribes who count "one, two, three, many" were just an urban legend!<p>By the way, the study doesn't show that "numbers aren't needed to count". It's not numbers they're talking about, but words naming numbers. That makes the finding a lot less sensational; it's not unusual for humans to work with concepts we don't have specific names for. Still, an interesting experiment.
