THE SCIENCE PICK

Stegosaurus!

A STOMP · UNDERDOG

You skipped a final pick. The facts still stamp a champ.

On forest, Stegosaurus wins. Stegosaurus is a lot heavier. Jaguar would still win some meetings at home.

In the wild, most animals skip a fight. We still judge who the bodies and the place would favor.

Science card: Jaguar 5 · Stegosaurus 2 · ties 1.

Your card: Jaguar 0 · Stegosaurus 0.

The last page follows the whole animal — body plus home — not one bar chart.
