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?
