It was my impression that many evolutionary studies compare ratite feathers to dino feathers, and note their similar structure, leading some to say that ratites are a kin to flighted bird, but didn't descend from them, but instead have a common theropod ancestor. 70.142.36.210 02:31, 9 February 2006 (UTC)
