THE SCIENCE PICK

Brachiosaurus!

A STOMP · UNDERDOG

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

On the ice, Brachiosaurus wins. Brachiosaurus is a lot heavier. Walrus 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: Walrus 5 · Brachiosaurus 3.

Your card: Walrus 0 · Brachiosaurus 0.

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