I think so, what about why idk cells can produce isulin and other cells cannot? what did u write for that
(I wrote random stuff about epigenetics too)
the one that was beside it on the new thing (the one with diff genus) because they came from the same main branch which meant they had a lower phylogenetic difference ( thats what I wrote)
