🧵 a non vertebrate ancestor of the fish?

how the FUCK could a balanoglossus (penis worm) share any genes with (lamprey eel)?
but still balanoglossus genes point out towards lamprey eel more than any other vertebrate
it is a hemichordate worm, it is 500 million years old and still lives
it has 6 gill slits, altough not visible, just like ancient fish had (they have it visible)
hemichordates do not have eyes but its possible they lost their eyes during 100 million years of evolving towards being like earthworms of the sea, as they do the same thing earthworm does on land, but hemichordate is still not related to earthwom in any way
it doesnt need eyes if its buried for all its life
in this gene comparison there was 33 organisms and all others are vertebrates and one hemichordate was thrown in for good measure
his genes should be completely different from vertebrates but what do you know, its has some percentage of clear connection to lampreys the most primitive fish

That's because balanoglossus represent an evolutionary link between invertebrates and vertebrates. So the evolution would look something like this:
Invertebrates -> Balanoglossus -> Lamprey -> other Vertebrates

I need to bring this knowledge forwards because no biology book will mention the similarity in between genes
Biology text books are only about basics of biology. Genetic relations are only known to biologists themselves and not found in books.
