🧵 this is how evolution went

I think here it is
1. Hydravulgaris
(even if hydra doesnt have eyes, some of distantly related medusas infact have eyes, hydra just probably lost its eyes as it doesnt need them)
2. Ragworms
(rag worm tentacles evolve into arthropod legs so ragworm is the closest resemblance of the ancestor of both insects and vertebrates, other types of rag worm evolved into fish)
3. Seaspiders->Seascorpions->Finally their land relatives 450 million years ago
(sea scorpions will then go extinct shortly after they had spawned on land, but sea spiders persist even to this day)

Every one of these is at the same stage of evolution, none of them descend from the others

how about this:
1. creature that looked EXACTLY like hydra vulgaris, 750 million years ago, but no relation to current day hydra vulgaris, evolved into ragworms
2. creature that looked 600 million years ago EXACTLY like platynereis ragworm, evolved into sea scorpion
3. Sea scorpion goes upon land some 450 million years ago when land life becomes a possibility (could be some other year also, it is known that fish emerged on land 330 million years ago but surely land was habitable at least 400 million years ago)
4. Wall-Harvestman of today most closely resembles the first land born sea scorpions. Meanwhile actual spiders have evolved further for hundreds of millions of years and are more distantly looking from their ancestral form.

arthropods evolved from lobopodians which looked like modern velvet worms.

and did the lobopodians evolve directly from something that looks like exactly like a ragworm?

hmmm
