And then humans came along to mess with em
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.

What are the alternatives, and how can we reduce their costs to match that of horseshoe crab blood?
I have done some more googling (I can’t stress this enough, I am just googling)
The top alternatives are rFC (genetically modified cells produce the required enzyme) and MAT (human monocytes do the detection) They’re more costly, picking ready fruit is easier than growing an orchard.
Also I should mention how new the alternatives are, they’re just (2018 is just now for me lol) getting their approvals and regulations so given time LAL will be replaced.

That sounds encouraging!
Subsidies
So they’ll use alternatives once the crabs go extinct.
Well… 😶
It’s like a more realistic representation of what Neo would see when he wakes from the Matrix

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

I came to mention the same. Static phenotype ≠ static genotype.

If anyone else is struggling, this reasonably basic article helped me https://sciencenotes.org/genotype-vs-phenotype-definitions-and-examples/
Sorry! We’re both biologists, we get nerdy.
No I love it - that’s why we’re here.
I learned something today and hope to gently explain it to my degenerating/conservative father (but let’s not get into that kettle of fustercluck!)
Much obliged ! I was just thinking these strings of letters kinda looked like words
Honestly, I’m pretty sure they post any old brain rot here and then have an AI fabricate supporting articles online just to mess with us…
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].
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 minute earth just did a great video about that https://youtube.com/watch?v=_skYZFmr0Lg
Science abhors a vacuum but it fucking loves a crab
Nature abhors a vaccuum
Nice doggie!

There’s no evidence for gods though.
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.
Me too. It’s a science meme community after all.
Yeah, I got it the first time.
Nice!
Yet some of them still managed to evolve into spiders…
They were bored one afternoon
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.
Fascinating creatures. TIL they are more closely related to arachnids than crabs.
How close are they to horseshoes?
Hihi…asking the most important questions.
How about hand grenades?
Lazy bastards
all extant species (except hu-men) be like: evolve? whats that. just livin out here.
