Roj47 Posted September 29, 2006 #1 Share Posted September 29, 2006 The earliest known bird had flight feathers on its legs that allowed it to use its hindlimbs as an extra pair of wings, a new study finds. The finding, detailed in the current issue of the journal Paleobiology, supports the theory that early birds learned to glide and parachute from trees before achieving full-fledged flight. "This paper puts forward some of the strongest evidence yet that birds descended from arboreal parachuters and gliders, similar to flying squirrels," said study author Nick Longrich, a doctoral student a the University of Calgary in Canada. http://www.livescience.com/animalworld/060...eryx_wings.html Link to comment Share on other sites More sharing options...
