Previous studies suggested that the animal walked on the ground, but Burnham&#8217;s team argues that the feathered back legs would have prevented this. <a rel=\"nofollow\"  href=\"http:\/\/www.pnas.org\/content\/104\/5\/1576.abstract?sid=092cdca9-eed2-47a2-bd10-e38379bddae9\">A 2007 study<\/a>, also in <em>PNAS<\/em>, said the dino probably flew with its two sets of legs set parallel, like a biplane. But Burnham, whose team did glider tests with their model microraptor&#8217;s wings in three different positions, says the biplane formation would have put too much weight on the creature&#8217;s head.<\/p>\n<p>Instead, he argues, the dinosaur would&#8217;ve taken off from the trees and glided like a flying squirrel. <span style=\"color:#1c39bb;\">&#8220;The controversy was that these animals couldn&#8217;t spread their hind wings to glide,&#8221;<\/span> Burnham says.<span style=\"color:#1c39bb;\"> &#8220;But we&#8217;ve been able to articulate the bones in their hip socket to show that they could fly&#8221; [<a rel=\"nofollow\"  href=\"http:\/\/www.livescience.com\/animals\/dinosaur-birds-glided-trees-100125.html\"><em>LiveScience<\/em><\/a>]<\/span>.<\/p>\n<p>The study adds to the debate over how flight evolved in the earliest ancestors of birds&#8211;did flight begin when some ground-dwelling creatures hopped and leaped upwards, or when tree-dwelling creatures began to glide between branches?
