Steven Spielberg's new documentary The Dinosaurs traces their entire evolutionary arc. The iconic T-rex and Triceratops everyone knows, but also the earlier versions, the strange in-between forms, the constant changes. You see how they went through one catastrophe after another, adapting each time, slowly improving and becoming something else.

What stands out to me is the scale of time. These transformations didn’t happen overnight. They took hundreds of millions of years. The dinosaurs we recognize are results of a process that had been unfolding for an almost incomprehensible length of time.

And then you compare that to us.
