Ancient birds flew on all-fours

Bird flight evolved from using front and hind limbs as wings, new fossil study argues

The earliest known ancestor of modern-day birds took to the skies by gliding from trees using primitive feathered wings on their arms and legs, according to new research by a University of Calgary paleontologist.

In a paper published in the journal Paleobiology, Department of Biological Sciences PhD student Nick Longrich challenges the idea that birds began flying by taking off from the ground while running and shows that the dinosaur-like bird Archaeopteryx soared using wing-like feathers on all of its limbs.


Teach the contraversy! :)

Thanks for the link.

I've heard of this for a couple of years. This isn't new, AFAIK.
