Why didnt THIS WORM evolve further?None of the worms did.Nobody evolved to level of insects, spiders, vertebrates.Poly chaete worms must have appeared 600 million years ago. But they didnt modernize themselves.The only ones to live on land are earthworms, who lost eyes in the process because they actually live underground and dont need eyes there.Meanwhile, earthworms distant relative, the bobbit worm, who never left ocean, is a monster but primitive one. Two highly developed jaws equivalent to insect or lobster jaws. And blood circulation like in fish.But thats all. No complex brain, no legs, no complex internal organs besides the heart and blood vessels.It remains very primitive altough most evolved in its group of animals.
>>16829535I guess there is no need nor pressure to change. There might even be selective pressure to stay the same..

>>16829535>evolve furtherEvolution has no direction. It does not have a goal. There is no "more" evolved or "less" evolved. Environments change, lifeforms change, ecosystems change. Within those circumstances, some lifeforms persist, others don't. This creates a new set of environmental conditions, a new set of lifeforms, new ecologies. Once more, certain lifeforms persist, others don't. Sometimes one trait is advantageous in one set of circumstances, and it persists in lifeforms. In other cases, that same case is disadvantageous, and disappears from the genetic record. Complexity in lifeforms is sometimes advantageous, sometimes it is disadvantageous when that complexity is dependent on a very specific set of environmental and ecological circumstances, which makes it easier for something to go awry and threaten the continued existence of that lifeform.
>>16829592unlike worms we have this:insects have legs, actually legs seem to be defining insect form, there are zero insects who try to become wormsinsects have super complex brain altough its extremely smallhowever insect has blood circulation system which is LESS evolved than in wormsalmost zero internal organs, its a miracly they can go on without thosesquids:squids have extremely advanced tentacles, altough zero legsthese tentacles are in many ways as useful as legs if not even more (they are not good in land though)squids have even more advanced brain than insectssquids have internal organs on similar development level as do worms (except for the brain which is better)
>>16829535because its environment said it doesnt need to evolve further
They did evolve further. They now control the majority of Indian minds to make them play with shit.
>>16829592>Evolution has no direction. It does not have a goalThis sounds like opinion. How do you prove this statement?

We probably had giant fucking creatures in the ocean that didn’t fossilize properly. There were probably truly giant squids or something far back enough. Giant worms were probably a thing, too.
>>16831611would you still love me if I was a giant no-fossil-record worm?
