Birds evolved from a small raptor like theropod.
Also, while I was at Yale, I had a job teaching kids at the museum.
In 1941 Richard Owen said that the dinosaurs were almost hot blooded.
As an undergraduate I held many small jobs as an illustrator.
I also got a chance to go to the American Museum in New York, which helped my interest.
Traditional dinosaur theory is full of short circuits. Like the antiquated wiring in an old house, the details sputter and burn out when specific parts are tested.
