We first like to mention the encephalization quotient for each of our animals. EQ is a general indicator of intelligence, like BMI for brains. It means the brain-to-body-mass ratio. And in this ...

Here are some animals’ brains ranked according to size. Researchers often use a ratio called the encephalization quotient (EQ) to get an idea of how much larger or smaller an animal’s brain is ...

One fateful day 66 million years ago, the dinosaurs — which had inhabited Earth for about 165 million years — got a nasty surprise: A roughly 9-mile-wide (15 kilometers) asteroid crashed into ...

And an enormous one at that, making the risk-benefit trade-off uncertain. With an encephalization quotient of 7.5 (which means a brain 7.5 times larger than that of average mammals such as dogs ...
