I cannot believe that

    the national geographic channel could show such a crappy documentary. :mad:

    I just saw "extraterrestrial" and it sucked. for those of you who haven't seen it, they give predictions about ecology on alien planets that is totally stupid..

    they had small organisms that were yellow and odd-looking (I can't remember what they were called) they said in the second stage of their life, that they all group together into a population. except, they don't call it a population..they call it a new organism which is just a cloud of small organisms. this was a "super killer" they were extremely dangerous. when they deour another species (which is supposed to be the most intellegent species on that planet) they sprout out of it into a flower. then, the flower releases spores that are said to be new bodies in the first stage..

    I'm not going to list every ecological flaw in this...

    Anyone else see this?

    I'm glad to hear you didn't like it, yomamma. I asked someone to tape it for me and she wasn't able to, so I was feeling bummed that I missed it.

    But the thing that you mentioned about organisms grouping together to form a new super-organism.. hmm.. I don't think it's all that implausible because, if I'm not mistaken, that's what a portuguese man o' war* "jellyfish" is - it's not one specific creature - it's several different organisms working together as a colony, each having different roles.

    This is true. I think a corral reef is an example.

    but a coral reef is not a single organism

    Maybe not a coral reef, but I know there are some organisms that do have that behavior.

    organism= a living thing that uses organs to perform functions that keep it alive. several animals is not the same thing as several organs. unless these animals combine into stomachs and lungs...it is not an orannism...

    It sounds like they have taken Dictyostelium discoideum as an example.

    Not if the individuals cannot survive biologically on their own.

    they recently did the same thing on the discovery channel. looks like ng ripped off their show lol, but i bet they didnt have big names like george lucas, stephen hawking and michio kaku lol

    If I'm not mistaken, cellular slime molds aggregate to form a colony of cells at certain points in their life cycle, but are fully capable of living separately.

    Oh dear...from your description, I wonder if I should dare look in the biology forum to see what sorts of topics and questions have come up after the airing of that. :uhh:

    An organism needn't have organs. Wikipedia define an organism as "an assembly of molecules that influence each other in such a way that they function as a more or less stable whole and have properties of life."

    this blob of species did not perform those functions. each one consisted of argans and performed it's own functios, without really iinteracting with the surrounding bodies
