"It is a basal organism, which by chance preserved the basal characteristics present in our common ancestor," Moroz said. "This shows that our common ancestor doesn't have a brain but rather a diffuse neural system in the animal's surface."

A reconstructed genetic record reported in the Nature article also implies that the brain might have been independently evolved more than twice in different animal lineages, Moroz said. This conclusion sharply contrasts the widely accepted view that the centralized brain has a single origin, Moroz noted

Okay so its right above DU on the tree of species?

I've been told this is how "science" works.
You find new evidence.....add that to your accumulated knowledge......rewrite theory....repeat.

"It's a tremendous surprise that this mysterious creature from the ocean will help us understand our distant past," said Leonid Moroz, What happened to the ape theory? Now it is all the way down to a worm. Just think, you eat the worm from an apple and you just may be eating some of your genes.

So, the deal is if chordates have brains and octapus type animals have brains and insects have brains, and the common origin critters didn't have brains, then we each have "evolved" our own brains ~ or managed to plug the right viruses into the right spots in our genomes to get brains.
Actually, the finding here, however you interpret it, is very important for expectations in xenobiology.
The latest thought concerning brains has been that since they arose only once on Earth, it would be unlikely for them to have arisen elsewhere in the universe.
Now they are saying brains popped up at least three times right here on Earth.
Makes'em common as dirt and something to expect space aliens to have too.

You know, it would be good if people could simply find new organisms without having to bring alleged ancestry with humans and Macroevolution into it.

I think they are trying to say that the origin of the human brain is NOT what they thought it was, but IS from a diffuse neural system in the animal's surface

I don't know about that!!

"...from a diffuse neural system in the animal's surface..so does that mean the worm was "write once read many"?

It has evolved perfectly.
No brains = you can't do anything stupid.
No gut = you can't overeat
No gonads = well, we just need to leave this one to our imaginations

Sounds to be like the evolutionary ancestors of Democrats.

YEC INTREP My interpretation is that most of these scientists read way too much into their findings.
As for the YEC, I'll leave that to someone else.

Something like 75% of our genes are matched in the worm's genes.
