Yet some of them still managed to evolve into spiders...
They were bored one afternoon
Fascinating creatures. TIL they are more closely related to arachnids than crabs.
How close are they to horseshoes?
How about hand grenades?
Practically identical.
Hihi...asking the most important questions.
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.
Absence of paleontological evidence of change in appearance does not mean evolutionary stagnation
Doesn't it? It doesn't seem obvious either way. Are you an actual paleontologist, or just guessing?
Molecular biologist.
It's mostly a matter of what we don't know. Paleontological evidence certainly shows that horseshoe crabs didn't change much in their appearance. However, we just don't know to what extent other aspects of their biology are as conserved. Therefore, it is just unscientific to say that horseshoe crabs are 'living fossils' or that they didn't evolve for millions of years. They may have, they may not haveOne minute earth just did a great video about that https://youtube.com/watch?v=_skYZFmr0Lg
And then humans came along to mess with em
Stupid life-saving copper based blood...
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.
It's like a more realistic representation of what Neo would see when he wakes from the Matrix
Nice doggie!
Lazy bastards
Science abhors a vacuum but it fucking loves a crab
Nature abhors a vaccuum
Heckin sea roomba
all extant species (except hu-men) be like: evolve? whats that. just livin out here.
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.
