The fact that there are very few fossils of soft bodied creatures kinda misses the point.
All the evolutionary diversity of molluscs is still alive. Squids, nautiluses, cuttlefish, snails slugs.
What’s the hypothesis here? An alien meteorite landed with 800 types of cephalopod, that just by chance share 97% of their DNA with slugs and snails that already existed on Earth?

What if the protooctopus is a common ancestor to the 800 types of cephalopods?
TheIvoryTower@lemmy.world 8 months ago
Then why are all those cephalopods so closely related to all the other non-cephalopod molluscs?

obviously other molluscs are tentacles budding off, they are independent after all.

Alien cephalopod had sex with molluscs? /s

The best scientific theory is the sexiest one, so yes.
