🧵 is invertebrates one big family

which can mix?
but vertebrates are the only group of animals that are different from invertebrates and therefore cannot mix with invertebrates?

here's what's probably going on:

-primitive worms release free sperm and eggs to sea water
-primitive crustaceans release free sperm and eggs to seawater

at one point during the course of 300 million years, crustacean sperm enters worm egg or vice verse and it actually was capable of combining into new life form, millions are born initially due to the amount of eggs and sperm, if had been a single individual, creation of whole race of beings wouldnt happen

the result?
-centipedes are born, which soon move to live on land, since they have never been found in oceans but there is definite proof they have existed on land for hundreds of millions of years

is there even remotely any proof?
well the genes of ragworm, which is probably 500 million year old primitive sea worm that still continues to live, has genes that resemble bot land centipedes, land earthworms, and various ocean worms and also a bit of a lobster

>with vertebrates such things werent possible, vertebrate eggs are very careful on what sperm they let in
