      I find it hard to understand, what special thing the blood has, that is not synthetically manufacturable. With most foodstuff companies trying to synthetically manufacture as much of the food as they can, what makes this “Near Threatened” animal, so important to harvest?

        I googled it for you, there is LAL which is a blood clotting agent (that exists only in the blood of horseshoe crabs) that reacts with the bacterial capsule which makes it important for vaccine safety tests. Alternatives do exist but ya know, money is more important to corporations than some animal’s life.

      Doesn’t it? It doesn’t seem obvious either way. Are you an actual paleontologist, or just guessing?

          It makes sense. I just wasn’t sure how likely it would be for species to evolve in significant ways over a long time without obvious changes to the shape of their fossils. Difficult to spot evolution happens a lot, apparently:

          Cryptic, or sibling, species are discrete species that are difficult, or sometimes impossible, to distinguish morphologically and thus have been incorrectly classified as a single taxon. Cryptic species are found from the poles to the Equator and in all major terrestrial and aquatic taxonomic groups [2, 3]. For example, a recent meta-analysis yielded 2,207 articles reporting cryptic species in all metazoan phyla and classes, including 996 new species in insects, 267 in mammals, 151 in fishes and 94 in birds [2].

          Yeah exactly. I’m not a biologist but I am aware that horseshoe crabs are harvested for their blood and its unique properties. How much evolution (in the last 450MY) have they undergone in terms of their immune system and other microbiological processes? We may never know but I think it’s quite a stretch to assume “none!”

          I would have to assume there’s some ecological pressure they’re either experiencing or shielded from. If they’re under environmental pressure, they are either exceptionally developed to endure environmental changes or they’re adapting to the environment in ways that don’t reflect in their physiology. If they’ve just found a niche biome where the ecological conditions are fairly static, and they’re well suited to the environment, what changes would you see other than some generic genetic drift?

    One of the best things I got to do as a kid was go down to horseshoe crab time at the shore at pet them and hear a science human talk about their fancy blood. The fancy blood of the horseshoe crabs, not the science human’s blood.

    all extant species (except hu-men) be like: evolve? whats that. just livin out here.

      There’s also no evidence that horseshoe crabs have individual names and understand the concept of evolution.

        We do have evidence that at least one species give their members individual names, and at least a portion of the members understand the concept of evolution

        So i would say we have more evidence for this meme being accurate than any god being real

        Fair point. Although one may say this is fine here for comic purposes.

        The same argument could be made about the statement “Gods perfect creation”.
        But I’d argue that the suggestion of a creationist god expands the distance to scientific contexts even more while simple speech bubbles are fine due to less ideological conflict potential.

        Admittedly, I am also rather allergic to religions, which is why I am having a difficult time with that part of the meme.

          Just for a moment pretend God banged so hard he created the Big Bang which create all life, and laugh at religion joke.

            Due to the “being allergic” part this is unfortunately not possible for me. But thanks for trying to provide me with a different perspective.
