    Don't Eat That Fish

    Don't Eat That Fish

    Dr. Sylvia Earle wants you to stop eating fish. It’s not because fish are endangered, though wild fish stocks in many oceans are very low. It’s not because they’re bad for you, though fish in many areas are exposed to poisonous substances in the water. It’s because they’re smart.

      “Fish are sensitive, they have personalities,” says the marine biologist. For Earle, eating a fish would be like eating a dog or a cat. “I would never eat anyone I know personally.”

      There’s a lot more to fish than meets the eye: they talk to each other, they like to be touched, and they engage in behavior that can seem very human. They can remember things and learn from experience. Earle and a growing number of animal rights activists see these as strong arguments against eating fish altogether.

      The activists also point out that fish feel pain and fish suffer horribly on their way from the sea to the supermarket. “While it may seem obvious that fish are able to feel pain, like every other animal, some people think of fish as swimming vegetables,” says Dr. Lynne Sneddon. “Really, it’s kind of a moral question. Is the enjoyment you get from fishing (or eating fish) more important than the pain of the fish?”

      Fishermen and (fried) fish lovers are skeptical. “I’ve never seen a smart fish,” says Marie Swaringen as she finishes off a plate of fish at a Seattle seafood restaurant. “If they were very smart, they wouldn’t get caught.”

      “For years, everyone’s been telling us to eat fish because it’s so good for us,” says another diner. “Now I’ve got to feel guilty while I’m eating my fish? What are they going to think of next? Don’t eat salad because cucumbers have feelings?”


    Animals Laughed Long Before Humans, Study Says

        As the human brain evolved, humans were able to laugh before they could speak, according to a new study.

        But here's the punch line: Laughter and joy are not unique to humans, the study says. Ancestral forms of play and laughter existed in other animals long before humans began cracking up.

        "Human laughter has robust roots in our animalian past," said Jaak Panksepp, a professor of psychobiology at Bowling Green State University in Ohio. Panksepp has studied rats and found that when they "play," they often chirp—a primitive form of laughter, according to the scientist. In an article to be published tomorrow in the journal Science, he makes the argument that animal laughter is the basis for human joy.

        In studying laughter, scientists have focused mostly on related issues—humor, personality, health benefits, social theory—rather than laughter itself.

        New research, however, shows that "circuits" for laughter exist in very ancient regions of the human brain.

        As humans have incorporated language into play, we may have developed new connections to joyous parts of our brains that evolved before the cerebral cortex, the outer layer associated with thought and memory.

        Researchers say that the capacity to laugh emerges early in child development, as anyone who has tickled a baby knows.

        There is ample evidence that many other mammals make play sounds, including tickle-induced panting, which resembles human laughter. Indeed, animals are capable of many emotional feelings, just like humans, some scientists say.

        "The recognition by neuroscientists that the brain mechanisms underlying pain, pleasure, fear, and lust are the same in humans and other mammals underscores our similarity to other species and is extremely important," said Tecumseh Fitch, a psychology lecturer at the University of St. Andrews in Scotland.

        In a 2003 study Panksepp and Bowling Green State University neurobiologist Jeff Burgdorf demonstrated that if rats are tickled in a playful way, they readily chirp. Rats that were tickled bonded with the researchers and became rapidly conditioned to seek tickles.

        Understanding the chirping of the rats may help scientists better understand human laughter.

        Robert Provine, a psychology professor at the University of Maryland in Baltimore, agrees there is an evolutionary continuity of laughter. Its origin is in tickling and rough-and-tumble play, he says.

        Provine, the author of Laughter: A Scientific Investigation, and other scientists have studied chimpanzees and found a link between their laughter-like noises and human laughter.

        "Laughter is literally the sound of play, with the primal 'pant-pant'—the labored breathing of physical play—becoming the human 'ha-ha,'" Provine said.

        By studying the transition between the panting of chimps and the human ha-ha, scientists discovered that breath control is the key to the emergence of both human laughter and speech.
