Evolutionary Biology

Multiple dinosaurs walk across a lush valley landscape. Several pterosaur-like creatures roam the sky, and two trees frame the image, as a hill looms in the background.

Why Were Dinosaurs So Big?

A grey tabby and white cat sits on a brown marbled floor, leaning to its side, in front of a yellow wall. Next to the cat sits an empty glass and a nearly empty bottle of brown liquid that seems like hard liquor. The cat’s eyes are half-open, with contracted pupils, making it seem, anthropomorphically, intoxicated.
