Tiktaalik continues to shed light on how fish evolved into amphibians.  This article show us the new evidence:
Tiktaalik

"WASHINGTON - An extraordinary fish that existed 375 million years ago had unique features in its head that helped pave the way for vertebrate animals to live on land, scientists said Wednesday.

Scientists for the first time described features in the underside of the skull of Tiktaalik roseae, the so-called “walking fish” discovered in the Canadian Arctic in 2004. It is considered an important transitional animal in the evolution of fish into amphibians, the first land-dwelling vertebrates."

The article goes on to say:

"Tiktaalik is seen as a forerunner of all land vertebrates including amphibians, reptiles, mammals and eventually people.
The scientists described key features in its head and braincase and the decline in size of a bone called the hyomandibula. In fish, this bone links the braincase, roof of the mouth and gill structures and coordinates their motions during underwater feeding and respiration.
As land animals evolved, the hyomandibula eventually became the stapes, one of the tiny bones in the middle ear.
Tiktaalik has features of some of the more primitive fish it lived with as well as features of the first four-legged amphibians that lived on land. Its fins had discernible wrists and elbows in an evolutionary step toward legs that could be used to walk around on dry land."

AS has been stated over and over, evolution is a fact, common descent is a fact.  The evidence is overwhelming and no biologist contests this.

That came in handy.

Yesterday, on one of my YouTube videos, someone asked why scientists never tell anyone about all of the transitional fossils I mentioned.   I said they do.

I went to ScienceDaily and they had an article about the a new fossil, of the earliest flying insect.  So I posted the URL.

Then I saw this one on Tiktaalik, and added it too.

So in one day - chosen at "random" by a someone else - I ran into 2 articles about fossils of transitional forms.  

But yeah, scientists never tell anyone about them :-)

Thanks a lot, man!

Evolution is so beautiful... If creationists only knew what they're missing. But i guess they could say the same about us. :P

Dinosaurs are cool enough. But more ancient creatures are much more interesting to me.

Scientists assert (by Lester):

Ha Ha. (...) I've told you people endlessly about my evidence but you don't want to show me yours - you just assert.

Would we see a mammal by the water's edge "suddenly" start breathing underwater(w/camera effect of course)?
