So like I know horseshoe crabs have been around nearly unchanged and all. And good for them!
But are you (general you, not op specifically) really trying to tell me that not once in their entire historical span of time on earth… not one single time did anything evolve from a horseshoe crab?
Clearly I’m not saying the whole species changed, but that is separate from an offshoot population evolving into something different. Which surely must have happened, no?
Weirdly enough, evolution isn’t random - it follows rules. We’re still figuring out what those rules are, but it does in fact reach a certain point, then lock down the genes.
Horseshoe crabs are chemically incredible, they’re extremely resilient and physically pretty good for their niche
I’m not saying you are wrong, because I’m open to new information, but that’s not ever been my understanding of how evolution works, and I’ve read a ton on the topic.
Evolution continues even if a species doesn’t obviously change over time. Unless it’s an asexual reproducing species, gene recombination ensures some level of diversity, and more opportunity for novel traits. But even a clonally reproducing species have a chance for mutations, they are just significantly more likely to be detrimental than useful.

We don’t talk about those cowards.
It probably did, you are right. Also, what about internal stuff. Who is to say that their plumbing hasn’t evolved considerably over the eons?

Maybe they are a genetic endpoint
Do you have any citations for that?

Wait, so it’s stops before ‘the heat death of the universe’? That’s bizarre!
