Could Hallucigenia be the echinoderm missing link?

Yeah, and that’s never going to happen, It’s a tiny idea in the grand scheme of things. Maybe in some odd point in the future it’ll be worth pursuing. That doesn’t, however, mean there’s a fundamental flaw. . .if there is it’s hidden behind a paywall somewhere.

I was hoping to get to a few clever questions (like ‘oh! But hold on, while the Sea Pig does indeed have pentaradial symmetry it actually DOES have two pairs of legs on the bottom, and only two sets of spines on the top, how does that work?’, which would’ve been a great observation!). That would’ve added a second mind to the process and helped enhance my knowledge.
