aliens
SCIENTISTS looking for aliens in space should be hunting them on EARTH, it has been claimed.
Prof Paul Davies said creatures totally different from life as we know it may exist on our planet.
The UK-born cosmologist, now in Arizona, believes they might not have DNA - meaning they would not have been found by usual life-detection techniques.
He called for searches for "weird life" in inhospitable places, such as hot, undersea vents.
Prof Davies said finding alternative life "would be the biggest discovery in biology since Darwin and evolution". - sun
