Why Dogs Are Smarter Than Cats
Being sociable has its advantages—across more than 500 mammal species, animals that lived in social groups had bigger brains than those that lived by themselves.
Evolutionary biologists had long assumed brain size increased in mammals in a more or less consistent fashion, with each species gaining roughly the same boost relative to body size over time. However, Oxford researchers Dr. Susanne Shultz and Professor Robin Dunbar have revealed in their new study that the truth is a bit more complicated, and it's actually the sociability of a given species that determines brain size. Unsurprisingly, primate brains grew the most over time, followed by horses, dolphins, camels, and dogs. All these creatures tend to live in stable social groups. Solitary mammals, including everything from cats to rhinos, showed much slower brain size growth over the same evolutionary period.

Progressive America would be half as big, but twice as populated as its conservative twin.
