>actually echinoderms aren't radially symmetrical because of this off-center piss hole Bullshit-ass animal, get your spiny ass OUT of Bilateria
>>5143920asymmetry is a feature, not a bug
Why did they evolve like this?
Never understood why none of these evolved proper eyes. I imagine they'd become something similar to proto mollusks
>>5144266They wasted their evolutionary history evolving into sessile forms and are currently too occupied with backtracking from it. It's honestly fucked up that they need to ditch a perfectly good bilateral larval form for some cnidaria wannabe bullshit as seen in >>5143924.
>>5144270The ones who kept that larval form went on to become other branches of life and crowd out the niche for anyone trying to get into the game late.
>>5143920tell me, do you have a liver on each side?a spleen?an apendix?gall bladder, duodenum, pancreas, stomach, aorta?you fucking pretend symmetrical worm
>>5143924they yearn to be internal organs
Comment>RETURN TO BILATERIAif you want a large swarthy man to rotate your guts 90 degrees on the axial plane
>>5144388I rotated your mom's guts 90 degrees on the axial plane, if you catch my drift
to think this could have been humans. all that clusterfuck biology and bizarre physiological gymnastics, just to have even less brainpower than a fucking ant. thse things suck. At least sponges and cnidarians have simplicity as their shtick and arnt trying to be complicated

>>5144270They wasted their evolutionary history evolving into sessile formsSeriously, had a perfectly workable bilaterian slug thing going on and then they pull this bullshit
Like seriously, come the fuck on, this shit lasted until the end-permian? 200 million years of this? This is the type of shit that's supposed to show up like twice in the burgess shale and never be heard from again
