I'm not sure if I buy the Chozo getting Metroids from that critter, they make it pretty clear that they viewed the impact of the meteor as a very bad thing, and went out of their way to seal it up as quickly as possible, and it subsequently wiped them out.
The Metroid Prime as Not-a-Metroid is a decent theory, since it is so physically different from all currently known Metroid mutations.
Most indications seem to point to Tallon IV being developed well after they'd been active elsewhere in the galaxy, and likely, with Metroids, so I really don't think they developed Metroids from Prime, and I'm still not even convinced there were any Metroids on the planet before the Pirates brought them. This all makes decent sense if you accept Metroid Prime as a non-metroid being that crashed into the planet, but it STILL doesn't cover the breach of the sealed crater.
