Dolphin Jumps Again with Artificial Fin 256

Posted by michael from the laser-not-included dept.
Ant writes "This Yahoo! News story mentions Fuji, a mother dolphin that lost 75 percent of her tail due to a mysterious disease, being able to jump again with the help of what is believed to be the world's first artificial fin. The 34-year-old dolphin held at Japan's largest aquarium in the southern island of Okinawa wears the rubber fin for about 20 minutes a day allowing her to jump and to swim at the same speed of other dolphins."

      In the current Survivor:Vanuatu one of the contestants has an artificial lower leg. He is one of the best competitors in the physical challenges. The only test that he seems to have a bit more trouble than the others in is walking a narrow balance beam. He was voted off last night after 29(?) days and making it to the final 8.

      Depending on whether you believe they actually live in that shelter on the beach for 39 days when the cameras aren't turned on or not, his leg doesn't seem to be having any trouble with the salt water, sand, dirt, etc. I'm actually very interested in seeing some interviews with him after the show ends on some of the particular problems he faced with it.

      Well, its not as if they went out and found a physically challenged wild dolphin, and laughing at Darwin, gave it an artificial fin. This was a captive dolphin that contracted a disease and lost some finnage. That's hardly a natural situation, and I don't think the long-term genetic health of the species will be affected.

      • That's hardly a natural situation, and I don't think the long-term genetic health of the species will be affected.

        Right, because humans exist outside of nature. While the fate of one dolphin is negligible in terms of evolution, humanity is part of nature. I've always found the "not natural" argument to be a fallacy that leads to wrong conclusions.

      " Like it or not, the weak are supposed to die out."

      Uhh... says who? I think you're taking that "survival of the fittest" a little too literally. There is no direction to evolution. In the long run it might be the case that the fittest survive most often, but this isn't necessarily the case on a per-individual scale.

        Just remember that "the fittest" is defined as whoever survives in their environment. So, this particular dolphin may have a cuteness adaptation that makes humans want to help her. While that wouldn't be a benefit in a humanless ocean, she doesn't live in a humanless ocean. It doesn't make any sense trying to decide who is the fittest beforehand. That is trying to put a human value judgement on a natural process. You do what you do. They do what they do. No need to worry about evolution. It'll keep on going without us. It's like that.

Many of their original behavoirs and appearences would have been detrimental to them while living with humans, and in their new environment these have been selected against.

    • It's a decent enough question, but I seriously doubt one artificial dolphin flipper has any effect at all on evolution. "Help" is a relative term of course and depends on your value system.

      For example, the US Park Service policy of putting out all forrest fires over the last many decades has resulted in a buildup of fuel for much more massive and devastating forrest fires. In "helping" forrests we've really hurt them.

      Well known but untrue. Although it's commonly refered as the "survival of the fittest" - which many people misunderstand as "survival of the strongest" - what modern science means is the "survival of the most adaptive". That is, species that can adapt fastest with the least amount of hazzle to changing environments and new illnesses have the biggest chances of survival.

      So I take it that you've never used antibiotics to fight an infection. You can't use "survival of the fittest" as a law of nature. The quote was actually made by an economist describing the buisness climate of the early 1900's, not by Darwin describing his theory of evolution. The two just have superficial similarities which is why people equate the two together. Remember, "fit" is a relative term compared to the environment at the time.

Think of it more like an ear, it's functional but it doesn't move. The part that moves is in her tail, and that part wasn't amputated. The fin only provided extra push (thus why she can still swim with the amputated fin, just slower and with more exertion). I imagine that once she got used to having it on it was ver
