When Niche Intesrests Collide This Is What Happens Lol - Tumblr Posts

So I'm sitting here watching Forensic Files and investigators were examining bone fragments under extreme magnification under a microscope to examine the osteon (the building blocks of the bone essentially) to check whether the bones were animal or human. Basically it boils down to this: human osteon tends to be rounder and evenly spaced out and animals tended to be closely arranged in a row-like structure. (There's a picture below the cut, for anyone interested. TW: bones, trypophobia)

All this got me thinking: If an Arrancars bones were taken under a microscope, would they show human osteon or animal osteon? Would it be dependent on their evolution at the time they became Arrancars? They were all transformed at different stages, it seems, so would that potentially affect the results?

These are the things that keep me up at night lol. Worse yet, I can only theorize instead of doing research because they aren't real😭😂

What do you guys think?
