I cant stop thinking about the fact that at some point during evolution there is some poor soul that was the first creature to ever poop. Could you imagine how traumatic it must have been to be the first living creature ever to have to poop :)

@freemo I love the way you illustrate it as an amazing experience. I think the "pooping" as you know it evolved very gradually. IIRC, even single cells eject material, so there's a long path from there.

@cobratbq yea, I am not defining pooping as just the expulsion of waste, that happens at every level. I am referring to pooping as the storing of waste in a sack that gets released at some later point. It presumes multicellular and the first evolution of a digestive tract. My guess is the first real poop was little more than a sack where cellular waste was collected so some water or other resource can be reclaimed before ejection.
