At first glance, human history is full of remarkable feats of intelligence. We invented writing. Produced incredible achievements in music, the arts, and the sciences.

But, as scientist Justin Gregg persuasively argues, if intelligence, as we understand it, is all that special, why don’t we see more of it present across the animal kingdom?
