In certain animals, the levels of intelligence can be compared with the respective brain sizes. Snell-Rood and Wick note two potential explanations for why the species in cities would have larger skulls than those in the country. Two-headed snakes are unlikely to survive in the wild as the two brains make different decisions that inhibit the ability to feed or escape from predators.

For the first time, a team has networked the brains of multiple animals … For the past 50 years, international animal cognition research has often related the use of tools such as rocks and sticks to cognitive abilities in animals. The existence of an enlarged neural canal near the hip region of huge dinosaurs like Stegosaurus was initially thought of as the second brain's location, to control the motions of the tail. How did our brains get so big? First, brain structure is more important than brain size, and human brains with their highly folded and complicated cortex can do things no other brains can.

No modern animal has two brains, unless it is a conjoined animal with two heads as a result of incomplete twin formation. Dinosaur brains and intelligence are interesting topics.
