[Jurassic World] Could they have just as easily filled the gaps in the Dinosaur DNA with DNA from birds?

Instead of lizards and amphibians.

Hello thank you for your interest in the Science behind Jurassic Park!

First off yes we could have filled those DNA chains in any number of ways, but the dinosaurs we grew up with had scales and so we decided that this was the image we desired for Jurassic park. We did produce a few test batches with bird DNA since we were told it would be "easier" and less "playing God." These test produced decidedly less scary feathered dinosaurs which frankly just looked silly. So we took the road less traveled and went with Frog and Lizard DNA despite the difficulties.
