I know most people don't give more than a wet slap about amphibians, but, as a long-time paleontology and missing-links connoisseur (I'm not French--forgive me if I spelled that wrong), I was very interested in this article (from Faux Noise, of all places) about a fossil that bridges the gap between frogs, salamanders and temnospondyls. Here is the opening paragraph of the report to Nature. Looks like there's one more missing link that Dempski and company will have to debunk. Is anyone keeping a running total?

Woohoo! That's from up near Seymour, where everyone's favorite Giant Toothy Killer Frog, Seymouria baylorensis, came from. Makes me want to go pirate fossils, almost.

FOX News had this, huh? That's funny. Anyway, interesting find. thanks for sharing. I also found the bit about the transitional frog mentioned at the end of the article interesting. Transitional Frog Lays Eggs on Water and Land | Live Science Edited by Deftil, : No reason given.

Deftil writes: FOX News had this, huh? That's funny. Actually, FOX's online SciTech news isn't very anti-evolution and ultra-conservative as you might think: they put up a lot of good evolutionary biology articles. Earlier this year, when another research paper came out saying Homo floresiensis was just a dwarf modern human, Faux Noise actually ran this article that consists of almost nothing but criticism, clearly fully supporting the notion that H.f. is a distinct species. Who would have thought, eh?

Could that be merely "market forces" at work? Rupert knows the internet reading crowd is usually more savvy and willing to check multiple sites before just accepting a statement, and so it strives to be more accurate in its purely online articles. Whereas the people who watch Fox News on TV are older people who don't use the Tubes as much, so they hold much more sway over those viewers. You'll notice the Sci Tech stuff never seems to get discussed on the TV...

That's one small step for evolutionists, one giant leap for creationists ...

Weird Crustaceans
Nothing to do with frog-amanders, but I was intrigued by this link from the page cited in the OP. It's another FoxNews science story.
quote:
Bizarre Crustaceans Undergo Evolution in Reverse Among the greatest mysteries in zoology for more than a century have been vaguely shrimp-like creatures known as y-larvae. Although these microscopic beasts are clearly young crustaceans, no one knew what the adult forms looked like. Now researchers may have solved this puzzle by dosing the y-larvae with a hormone that forced them to go through a growth spurt. The result ” simple, pulsing, slug-like masses of cells that were "mind-blowing" to the scientists. These surprisingly simple creatures ” far simpler than their larval stage ” may be parasites found worldwide.
There is another link on the page to a video of the adult emerging. This is what I love about biology; every time you think you have a handle on it, something new and unimaginably weird comes along.

Re: Weird Crustaceans
Very interesting clip. One can also see a similar effect in the creatures known as tunicates or urochordates which start life in a larval stage similar to the amphioxus but the adult creature has lost also chordate features and is a sessile creature resembling a sponge with 2 syphons one for food intake & the other for excretion.

D minor chordates?
... a larval stage similar to the amphioxus but the adult creature has lost also chordate features and is a sessile creature ... This also makes me think of the current theory for the origin of chordates from a larval stage that never reaches maturity before reproduction.
