Dolphins Are Nearly as Clever as Humans

In The Hitchhiker’s Guide to the Galaxy, the dolphins know to leave Earth before the planet is destroyed—and it looks like Douglas Adams was on to something.

No, the planet isn’t in immediate peril (depending on your definition of “immediate”), but dolphins really are geniuses, second only to humans in intelligence, according to a new study.

This study revealed that the brain cortex of dolphins has the same complicated folds associated with human intelligence, and it has the scientific community buzzing. Thomas White, professor of ethics at Loyola Marymount University, argues that dolphins (i.e. “non-human persons”) deserve rights and “qualify for moral understanding as individuals.” PETA couldn’t agree more! And because we wouldn’t force our relatives to live in cages tanks, we’re writing a letter to the National Marine Fisheries Service, asking it to place a permanent ban on issuing permits allowing dolphins to be captured and used as attractions at theme parks and resort hotels.

Dolphins are thoughtful animals with distinct personalities, and each dolphin has a strong sense of self. They think, plan, and communicate with one another. In the wild, they spend their entire lives in large groups; removing them from their natural communities is traumatizing and often results in stress-related illness and premature death. If we don’t start treating our cognitive cousins with more respect, in the end we might really be left holding that note that reads, “So long, and thanks for all the fish.”

“Almost all of us grew up eating meat, wearing leather, and going to circuses and zoos. We never considered the impact of these actions on the animals involved. For whatever reason, you are now asking the question: Why should animals have rights?” READ MORE
