Baiji River Dolphin May or May Not Be Extinct

ozmanjusri writes "Major news outlets are reporting that after 20 million years, Baiji (Yangtze River Dolphin) are now officially extinct. This is apparently actually old news; it was announced on a Baiji conservation website in December of last year. One outlet, though, is claiming they may not quite be completely dead yet. The same scientist that filed the report leading the the declaration of extinction is still hopeful: '"This is only one survey and...you can't have a sample in a survey, so you cannot say the baiji all is gone by the result of only one survey," he said. "For example, there is some side channels or some tributaries [where] we cannot go because of a restriction of navigation rules, and also we don't survey during the night-time so we may miss some animals in the Yangtze River." Professor Ding says based on anecdotal evidence, he remains confident the dolphins are still out there. "I'm pretty much sure there are a few of them left somewhere in the Yangtze River," he said. "I keep receiving reports from fishermen, they say they saw a couple of baiji somewhere, sometime."'"

    This is apparently actually old news; it was announced on a Baiji conservation website in December of last year. I'll do you one better than that, it was apparently reported on fucking Slashdot too.

    Seriously, what is wrong with you people? Are you purposely making fun of yourselves? Because to those of us who aren't in on the joke, which is most of us I guess, it looks like the site is run by a bunch of fucking dumbasses.

    that there were 11 in captivity a few years back (they all died), they were trying to breed them in captivity. but they took tissue samples

    please, please, please someone tell me the chinese have some of those tissue samples in liquid nitrogen. given some technological progress then, we might be able to bring the baiji back to life in a century or so

    otherwise, the chinese deserve international sanctions for losing some of our shared world species diversity. it should be a un mandate with economic consequences that countries are responsible for the lifeblood of the species in their territories

    not to mention the fact the chinese need to apologize to their ancestors for losing a part of their heritage. the baiji is a potent chinese symbol to the chinese themselves, and all of china is a little diminished today if the chinese actually neglected something so important to their national identity to the point of losing it permanently. china's history with environmental protection is deplorable. this takes it to the level of moral outrage

    but nevermind this cranky westerner. i'll bet my life any random chinese person could better articulate the shame and anger at this horrible crime and tragedy, against china, by the chinese themselves

      So it's okay if I track you down and shoot you? After all, human beings die all the time. They did before I started locating strangers on the internet and shooting them, and they'll still die long after my bloody killing spree is ended by my death. It's not that big a deal, right?

        Note to parent poster: Death by natural causes is different from death by human intervention. The same goes for collective deaths, A.K.A. extinction.

      The species will never be viable again. Even if there are living specimens, even if there are tissue samples, the gene diversity is way too small to sustain a healthy population. You might be able to create a few in a lab but they will not be good for anything more than curiosity. As for sanctions against China, that is just outwardly ridiculous. UN mandates? You do know that China has veto power, being a permanent Security Council member, right?

      It might do you some good to educate yourself on these kinds of things before you start your eco-babble.

      And for the Chinese people, who are you to speak for them? I'd wager that the majority of Chinese never heard of these dolphins prior to the extinction report -- in much the same way that few Americans even realized that there was an Alaskan wildlife refuge, prior to the controversy over drilling there. It's a disservice to the Chinese for you to try to use them to further your personal agenda. Don't do it again.

    we caused it. human beings are now the managers of this planet. we're powerful enough to destroy it. so for better or for worse, we have to talk about what we can do, and what we are doing. and if we do something wrong, like cause the extinction of culturally significant animal, then we need to be angry about that and see if we aren't doing the same to some other species

    but you go ahead and talk about it's all so like disconnected man... nothing matters dude, yeah

    if you don't fucking care, then shut the fuck up, and leave the conversation to people who do care

    otherwise, if you open your mouth on the subject, then you do care

    so make up your mind:

    1. it doesn't matter. so prove it by shutting up
    2. it does matter. so go ahead and talk... about how it matters

    if you open your mouth again, when the words come out of your mouth, try not to be a moron

    See, there's a big difference between mostly extinct, and all extinct. Now, mostly extinct: they're slightly not-extinct. All extinct, well, with all extinct, there's usually only one thing that you can do...

    In all seriousness, with so few members of the species, they're effectively extinct, and that's what counts. There may be one or two, but there's zero chance they'll balloon into a viable population. Even if we save genetic samples, we're decades, if not centuries, away from being able to reproduce an entire species, if we can even do that. Even if we have tissue samples from twenty different dolphins, and reproduce them through some hypothetical cloning technique, I'm not convinced that's enough genetic diversity to sustain the species.

      An organism, particularly a mammal, is far more than its own DNA. Humans have 10 times as many bacterial cells in our bodies as human cells. Dolphins are no different. A baby dolphin no doubt gets cultures of all sorts of bacteria from its mother's milk. Unique symbiotic organisms live on the skin, in the gut, even in the blood in some animals.

      Further, the species is adapted to a particular ecological niche - in this case, the Yangtse River.

      Further, particularly in mammals, there are learned behaviors that are not genetically-based, which can include food-finding/gathering/hunting techniques, predator-avoiding techniques, mating behavior, child-rearing behavior, and so forth.

      If you want to recover a species from its DNA, it is necessary to reproduce all of the co-dependent species on which it relies. You could maybe get a different species of dolphin to act as a surrogate mother (freshwater dolphin would be necessary, I'd think), but it would have the wrong stomach flora, the wrong hormones in its uterus and breastmilk, the wrong rearing behaviors.

      What you'd get as a result wouldn't be the species you were trying to save. Not quite, anyway.

      We could probably maybe recover an extinct bacterial strain from its DNA today. Recovering something as complicated as a dolphin is, I'd guess, a century or more out, if it is possible at all: and it may not be possible at all.

    Extinction is pretty serious, regardless of whether that species matters to us or not. Congratulations, you've discovered a whole new category of "shallow"... worsened by the fact that apparently the main "cultural significance" of this animal is/was that it's tasty enough to fish into extinction. There's a Catch-22 for you.

    I'm by no means a greasy-haired wild-eyed foaming-at-the-mouth green-nazi hippie douchebag, pretty nearly the opposite in fact, and I certainly don't buy into the "stewards of the planet" bullshit, but extinction that is pretty clearly caused by human activity -- worse yet, incidental and easily avoided activity -- still makes me queasy.

    The point I'm trying to make is that extinction is so serious that whether the species was useful or important to us or not is completely irrelevant.
