Let's start with, Darwin's statement on stasis. YECs toss out his statement, pretending that the idea is new one and a departure from evolutionary theory. Yet Darwin discussed it his book over a hundred years ago.
From AIG:
Contrasted with Darwin’s view of a gradual process of change acting over vast ages of time, others have seen the history of life on Earth as one of giant leaps of rapid evolutionary change sprinkled through the millions of years.
But as you just learned...
But I must here remark that I do not suppose that the process ever goes on so regularly as is represented in the diagram, though in itself made somewhat irregular, nor that it goes on continuously; it is far more probable that each form remains for long periods unaltered, and then again undergoes modification.
Charles Darwin, On the Origin of Species, Chapter IV, Natural Selection
You think the people at AIG have the same excuse you do? No, they aren't ignorant of the theory; they just threw out Darwin's comments and pretended he never said them.
So am I. I already showed you how they tossed out part of a comment by astronomers who showed that the number of SNRs is not a problem for an ancient universe, and then presented the edited result as evidence that they though the opposite. Would you like to see that again, or would you like to see some more new ones?
If that bothers, you, it was probably a bad idea for you to try it. The "Gish Gallop" only works when there's limited time to shoot down all the YEC stories. On a message board, anyone can take the time to shoot them down one at a time. So it's a waste of your time tossing out all those falsehoods.
And I'm a very patient guy.
You're going to embarrass yourself, again...
Example:
A gene, not "material." And as you learned, the results produced the same sort of down feathers we seen on early dinosaurs:
Alligators are descended from the same ancient reptiles as birds, and as evolutionary cousins of modern birds their scaly skin served as a stand in for dinosaurs.
After performing a complete genetic analysis of chickens and alligators as they develop in eggs, the researchers identified key genes involved in feather formation.
They then placed these chicken feather genes in alligator eggs, with the goal of prompting the scales on the growing reptiles’ skin to develop into feathers.
As a result, some of the scales grew into structures “similar to the unusual filamentous appendages found in the fossils of feathered dinosaurs," said Dr Chuong.
Scientists have tried to create alligators with feathers
Alligators still have genes for forming feathers. It takes only one gene to restore that ability. I've already shown you this. Did you think everyone forgot?
No one is clever enough to hide all that evidence. No matter what you do, it's a hopeless endeavor.
So Darwin believed in a form of punctuated equilibrium. they still cannot prove stasis for eons. Nor can they prove rapid speciation! According to studies mutations are constant! Eldridge and Goulds theory fell out of favor and is not widely supported as it once was. But it just shows thatwe have a buffet of beliefs in evolution to choose from.
Well you said but you cannot show! Saying is one thing-that is a hypothesis. Now back upi teh facts to prove it.
But other evolutionists say scutes and feathers, while having many identical geneitc material are still different enough than one gene! If you could show a croc with feathers that would be nice! Buit even with intelligent design and handcrafting an evolutionary experiment- they still could not produce a feather in a croc.
Yes they produced a feather like appendage. feather like is not exactly a feather and it took remarkable manipulation and careful planning at precise stages of embryonic development! Not exactly what you call random undirected mutations. That is Dawkin Deception! And it took more than one gene.
For the research study, the team performed a complete RNA transcriptome and DNA genomic analysis of developing chicks and alligators to identify their gene expression differences and the key genes in scale or feather formation.
Next, they placed these unique chicken feather genes within alligator eggs, carefully turning them on or off underneath their growing skin to reawaken an ancient programming that can turn scales into feathers.
"Our analyses led to the identification of five morpho-regulatory modules that are essential for modern feather formation," said Chuong. "We propose that these modules may originally evolve as different strategies for better adaptation. Eventually, the integrative combination of five morpho-regulatory modules achieves the highly successful feather architecture today, allows the Ave class to claim most of the open sky as their ecological niche."
These key circuits lead to the budding and elongation of appendages, follicle with stem cells and dermal papilla to allow cyclic regeneration, barb ridge formation with different branching forms, and specific feather keratin differentiation.
Some molecules could only induce one of the five criteria, e.g., the Sox2 gene can turn on feather budding and totally inhibits scale formation, while Grem1 can induce barb-like branching.
"Other molecules, such as retinoic acid or Sox18, have a greater ability to induce scutate scales to form feather-like skin appendages," said Chuong. "These feather-like appendages display all five criteria defining feathers, suggesting that they act at a higher hierarchical level in this evolutionary pathway."
These master regulators may have been the very first genes to adapt during ancient archosaur evolution and gain a newfound ability toward the making of today's complex feathers.
"Intriguingly, some of these phenotypes are similar to the unusual filamentous appendages found in the fossils of feathered dinosaurs."
Inspired by the "flying dragon," Ping Wu wants to challenge alligator scales to form feathers. By forced expression of sprouty and beta-catenin, genes they found to help convert chicken scales to feathers, they are able to cause the formation of elongated scales in alligator embryonic skin.
The study significantly adds to the growing list of genes and molecules known to induce
feather-like structures in birds and has established a powerful new system in alligators to test and further explore the evolution of flight.
