A team of scientists, including researchers from the California Academy of Sciences, has reconstructed a detailed "tree of life" for turtles. The specifics of how turtles are related -- to one another, to other reptiles, and even to dinosaurs -- have been hotly debated for decades. Next generation sequencing technologies in Academy labs have generated unprecedented amounts of genetic information for a thrilling new look at turtles' evolutionary history. These high-tech lab methods revolutionize the way scientists explore species origins and evolutionary relationships, and provide a strong foundation for future looks into Earth's fossil record.
Research results, appearing in Molecular Phylogenetics and Evolution, describe how a new genetic sequencing technique called Ultra Conserved Elements (UCE) reveal turtles' closest relatives across the animal kingdom. The new genetic tree uses an enormous amount of data to refute the notion that turtles are most closely related to lizards and snakes. Instead, authors place turtles in the newly named group "Archelosauria" with their closest relatives: birds, crocodiles, and dinosaurs. Scientists suspect the new group will be the largest group of vertebrates to ever receive a new scientific name.
There go those nasty evolutionists changing things on creationists again. Can't they every get their static dogma right the first time?
What's interesting here is that this involves new technology, a more "High Def" version of sequencing that allows scientists to see more in the DNA than before.
Another test of the theory of evolution for explaining the diversity of life -- is it nested hierarchies or something else? A test of previous DNA sequencing to see if they got it right.

The UCE technique used in high-tech labs allowed scientists to move beyond years of speculation and place the Archelosauria group in its rightful place on the reptile tree of life. UCE has been available since 2012, yet scientists are just beginning to tap its potential for generating enormous amounts of genetic data across vertebrates.
"Calling this is an exciting new era of sequencing technology is an understatement," says Brian Simison, PhD, Director of the Academy's Center for Comparative Genomics (CCG) that analyzed the study's massive amount of data. ...
"In the space of just five years, reasonably affordable studies using DNA sequencing have advanced from using only a handful of genetic markers to more than 2,000 -- an unbelievable amount of DNA," adds Simison. "New techniques like UCE dramatically improve our ability to help resolve decades-long evolutionary mysteries, giving us a clear picture of how animals like turtles evolved on our constantly-changing planet."
Major findings also resolve an evolutionary mystery surrounding softshell turtles -- a bizarre group of scale-less turtles with snorkel-like snouts. Until now, studies linked softshell turtles with a smaller semi-aquatic group called mud turtles, despite the fact that softshells appear in the fossil record long before their mud-loving counterparts. The Academy's study places softshells in a league of their own on the evolutionary tree, quite far removed from any turtle relatives. Their long independent history helps explain their striking looks as well as their ancient presence in the fossil record.
"I have been working on the evolutionary relationships of turtles for over 20 years using a variety of methods," says Parham. "Fossils are essential for showing us what extinct turtles looked like, but also in letting us know when and where they lived in the past."
Parham notes that studying turtle fossils -- particularly the physical features of their bones -- hasn't always painted an accurate evolutionary picture of turtle relationships across continents and through time. "The turtle tree of life based on fossil turtle anatomy didn't match up with the timing of their appearance in the fossil record, as well as their geography," Parham says. "But the tree of life generated at the Academy's CCG is consistent with time and space patterns we've gathered from the fossil record. These new testing techniques help reconcile the information from DNA and fossils, making us confident that we've found the right tree."
There were a lot of unknowns, a lot of gaps, in the fossil record and the new data still meshes with the fossil record in time and space.
Darn, evolution passed another test ...
Enjoy

Darwin and Wilson, Wrong Again.
Oh you evolutionists will just twist anything to hold up your dead theory. This is not the refinement your dark evil scientists are trying to make it out to be. What this says is that, again, for the umpteenth time, your vaulted evolution was wrong. Wrong, wrong, wrong. That little group of the turtle kind had to be moved from this little twig over here to that neighboring little twig over their. Your atheist scientists had it in the wrong place for all these decades. Ever cents Darwin, or that other Darwin guy, Wilson whoever, put it their.
And look at that last statement you made. The fossile rechord is full of wholes as you no and is wrong, wrong. And here this new analysis technique confirms this? Oh that is rich. You just shot your errant dead atheist theory in the head.
All you need do is read the One God Authorized KJV Bible. The whole of creation is in their. And in the bible code, buried in the proven mathematic encryption of the Holey Words is the complete plan of God’s creation. That is what these atheist scientists should be studing, not a dead theory gone bad. Trust me on this. I no the Bible code is their and what it says. I read it somewhere on some Bible cite. Poe, I think, was the guys name. No I’m not going to look it up for you. Do your own work. That’s Poe as in a P with an oh sound after it.
