It’s not just man’s closer primate relatives that exhibit brain power. Dolphins, dogs and elephants are teaching us a few lessons, too. Dolphin brains involve completely different wiring from primates, especially in the neocortex, which is central to higher functions such as reasoning and conscious thought. Dolphins are so distantly related to humans that it’s been 95 million years since we had even a remotely common ancestor. Yet when it comes to intelligence, social behavior and communications, some researchers say dolphins come as close to humans as our ape and monkey cousins.

In recent years, animal researchers have found that thought processes in critters aren’t a matter of how closely related they are to humans. You don’t have to be a primate to be smart.
