Genetic analysis of an obscure, worm-like creature retrieved from the depths of the North Atlantic has led to the discovery of a new phylum, a rare event in an era when most organisms have already been grouped into major evolutionary categories.

"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.
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.
and never never admit that you were wrong before!
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.
This could be the "New theory of compounded circular evolutionary reasoning".
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.
Ping
I agree, but it seems with every new find, fossil or living, there is a race to claim something that has significant meaning.
"The Xenoturbella does not seem to have a brain, gut or gonads, making it unique among living animals".
YEC INTREP
so does that mean the worm was "write once read many"?
"The Xenoturbella does not seem to have a brain, gut or gonads, making it unique among living animals".
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
"does not seem to have a brain, gut or gonads"
Sounds to be like the evolutionary ancestors of Democrats.
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.
-Just think, you eat the worm from an apple and you just may be eating some of your genes.-
Something like 75% of our genes are matched in the worm's genes.
