Did dinosaurs evolve from birds?
You may have heard that dinosaurs evolved from birds. What evidence is there to support this?
According to http://www.businessweek.com/bwdaily/dnflash/november/new1115d.htm a bird-like creature lived 75 million years before the dinosaurs.
Now, that makes it hard for dinosaurs to be the ancestors of birds; the descendants would have lived 75 million years before their ancestors.
