Paris Zoo Unveils the 'Blob,' An Organism With No Brain But 720 Sexes (reuters.com) 156

Posted by BeauHD from the single-celled-organisms dept.
The Paris Zoological Park on Wednesday showcased a mysterious new organism, dubbed the "blob," that has no mouth, no stomach, no eyes, yet it can detect food and digest it. The blob also has almost 720 sexes, can move without legs or wings and heals itself in two minutes if cut in half. Reuters reports: "The blob is a living being which belongs to one of nature's mysteries," said Bruno David, director of the Paris Museum of Natural History, of which the Zoological Park is part. "It surprises us because it has no brain but is able to learn (...) and if you merge two blobs, the one that has learned will transmit its knowledge to the other," David added.

The blob was named after a 1958 science-fiction horror B-movie, starring a young Steve McQueen, in which an alien life form - The Blob - consumes everything in its path in a small Pennsylvania town. "We know for sure it is not a plant but we don't really if it's an animal or a fungus," said David. "It behaves very surprisingly for something that looks like a mushroom (...) it has the behavior of an animal, it is able to learn."

      It is so wide, that it's pracically useless for coming up with commonalities between one of its "sexes" and one of our own.

    • My best guess (and I'm just spitballing here because TFA doesn't give any answers and I couldn't find anything scientific making that claim) is that they're confusing strains with sexes to drum up clicks. If it can reproduce asexually and sexually, but cannot reproduce sexually without a mate, than it cannot reproduce sexually with a genetically identical, asexually produced individual either. So to reproduce sexually, you need another, different strain. It sounds to me like they're confusing strains for

      The nature is quite surprising at times for us humans limited to our experience, but there are more sexes then 2 for some organism, and it comes with enormous advantage for them. Think from the evolutionary perspective, as all it counts is to survive and have energy to have offsprings, now, a human enters a "room" (filled with random selection of the same species) and theoretically can have offsprings only with half of the individuals, if an organism with 3 sexes enters a "room" it can have offsprings with 2/3 of individuals, and so on. Some organism can change their sex depending on what is needed, e.g. the Nemo fish (Ocellaris clownfish) - sorry for ruining the story. Now, it is hypothesized that humans (and in general mammals) ended up with 2 sexes due to high specialization of each, which logically leads to only 2: the best at delivering genetic material and the best of having offsprings.

      Lastly, what is a sex - it's all about speeding up evolution by exchanging/mixing genetic material between the most adapted individuals, self reproducing organisms can only rely on natural mutations, thus obviously having a possibility to exchange genetic material gives an organism advantage. An interesting fact is that e.g. bacteria, even though they just multiply by divisions, they can exchange genetic material "sideways", i.e. just by picking it up from the environment, which together with super fast generations give them substantial adaptation to changing environment.

      • >if an organism with 3 sexes enters a "room" it can have offsprings with 2/3 of individuals
        I think that depends on the species - with slime molds any sex can reproduce with any other sex (and I think the number of sexes may change with species - I seem to recall 10 to 40 sexes being typical for them). I'm pretty sure some species need a member of each sex, or at least a quorum, in order to reproduce but I can't think of any examples offhand. That obviously reduces the ease of reproduction, but increas

        • I think that depends on the species - with slime molds any sex can reproduce with any other sex ...

          I think it's what I wrote - more "genders" -> more chance to find a mate withing a group of individuals of the same species:
          - 2 genders -> 50%
          - 3 ... -> ~66%
          - 4 ... -> 75%
          - 720 -> 99.8%

          Of course that raises the question - if any two nonequivalent genders can reproduce, then obviously their reproductive system is very flexible, so why have genders at all?

          To speed up evolution by exchanging genetic material -> improve chances of species survival by faster adaptation to a changing environment.

          The nature is even more astonishing then I wrote, e.g. Comodo Dragon females can give a male offspring without any male involvement if needed (e.g. no males availabl

      If I remember right all it means is that when 2 of these meet to reproduce sexually they have to be of different sex type. If 2 of the same sex type meet they can't reproduce together.(I'm thinking both will produce spores after mating though.)
      • More akin to blood type for us I think

      • Exactly right.

        Except that I don't think there's any mating going on, any more than with plants, less mobile molds, etc. As I recall (and I don't recall the terminology) individuals release (hemi?)spores, and when spores from two different genders come in contact they fuse to form a complete spore that's able to grow into an adult.

    When likely you have been eating and drinkng many microorganisms with such properties just this morning.

    There are single-celled organisms, that have organelles, or even less, just clusters of molecules, that can detect things like chemical gradients, light, etc, move or eat with just changing the shape of their body and passing chemicals through their membrane, and learn in the simplest way by holding internal chemical states or charges etc.
    Also, you can define sexes conveniently how you like. It's not like they got a penis and vagina or sperm and eggs that would make the analogy make sense.

      In this case, it's not a microorganism, although it has one-celled stadii. Slime molds are macroscopic organisms, easily to see with the bare eye. It's more that the normal definition of single cell organisms doesn't make much sense with slime molds as they can create extremely large cells (the largest every grown in a lab was 5,54 square meter!), and those cells can contain thousand cell nuclei. And then the once single celled organism can split itself into a thousand cells at once.

    I have no idea what it means by '720 sexes' but I'm going to guess the truth is more mundane than they're making it out to be. Probably means 720 strains or genetic combinations that cannot reproduce with identical strains but can with any other strain, or something like that, which makes sense for something that can also reproduce asexually. TFA doesn't say, and I can't find any reasonable articles explaining the 720 sexes thing.

      Same thing as is usually meant - two members of the same sex can't reproduce. Two members of different sex can.

      For humans, we have two genders, which means when you encounter another person there's a (2-1)/2 = 50% chance that they're a different gender so that you could reproduce together if you wanted to.
      For this species of slime mold, there's 720 genders, meaning that if two individual meet there's a (720-1)/720) = 99.86% chance that they could reproduce.
