Sometimes in science, you solve one mystery just to create another. So it goes with Bigfoot.
After creating a stir last October with preliminary results, an international research team has published an analysis of dozens of hair samples from mystery animals around the world. None reveal the existence of a yeti or Bigfoot, reports Bryan Sykes, an Oxford University geneticist well-known for his research on human evolution. But two hair samples point to a possible new and (you guessed it) mysterious species: a bear roaming the Himalayas that may be related to ancient polar bears.
