For example, theres this sea slug that I found out eats algae, which is normally exactly what you think is usual for an underwater marine animal, but guess what?
IT USES THE CHLOROPLASTS FROM THE ALGAE AND THEN GAINS THE ABILITY TO USE PHOTOSYNTHESIS AS A SLUG VIA ABSORBING PLANTS
I understand that, I still think its a bit too much metaphysical woo without evidence, and it wouldn’t be “truly” you so to speak.
