Evolution happens.

I found that out for certain the day I met a Tyrannosaurus X.

He had weak eyes, massive jaws, and stubby little arms.

He was cold-blooded. Scaly-skinned. Exclusively carnivorous.

I was intrigued. I asked for a blood sample. He roared.

He was the missing link, the old fossil.
