This site presents the idea that modern birds developed from pterosaurs (rather than land-based dinosaurs).
This is a credible alternative to the current land-based dinosaur to bird theory.

Questions?
If anyone has questions, comments or objections, feel free to submit them. I will do my best to answer them
It does not have to "come through the skin". Just think about the gene switch being turned off that produces the non-actinofibril part of the membrane. And all that is left then is the thick band of patagium material close to the body with the actinofibrils continuing to extend from it.
Do people see the game that Boomer Bower is playing? He began with a question and it has been answered. Instead of acknowledging that, he moves on to demand reference support for the idea. But the whole point of this entire blog is that I am presenting new ideas that are not part of the mainstream. What I have done is shown how the ACTUAL EVIDENCE that I reference, fully supports the point I am making.
I believe you did bright resolution the moment when you selected this theme of this article over here. Do you mostly compose your blog posts all by yourself or maybe you have a partner or even a helper?
Here is a summary of the basic ideas of this site: Birds developed in a lineage which extends from protopterosaurs (eg. Sharovipteryx) to pterosaurs (eg. pterodactyls) to primitive flying birds (eg. ichthyornithes, enantiornithes etc.) to modern flying birds (Neognathae) and modern flightless birds (Palaeognathae) AND The category called "coelurosaur dinosaurs" should include only the actual dinosaurs (eg. Tyrannosauroidea etc) and not birds AND The creatures called "maniraptor" (specifically those from Aviremigia to the present) are not dinosaurs but flying, andsecondarily flightless, birds, within the pterosaur to bird line.
AND
The fossil record does not support the purported dinosaur-to-bird idea. The fossil record does support the pterosaur-to-bird idea.
Note
This site presents the idea that pterosaurs (rather than dinosaurs) developed into modern birds. This is not an "evolutionism" vs. "creationism" issue. An "evolutionist" can say that the pterosaur to bird developments are due to neo-Darwinian means (random mutation and natural selection). On the other hand, a "creationist" can say that those developments are the acts of a higher intelligence. This site does not take a position on the "evolutionism" vs. "creationism" question.

Philosophy and Such
Like most people, I have philosophical ideas that go beyond the nuts and bolts of the scientific analysis of the origin and development of birds. There are larger questions that philosophers have grappled with since the most ancient times. If anyone is interested in my take on those more philosophical ideas, click here. But please realize that all the ideas of this site are pure materialist, scientific ideas supported by physical evidence and scientific studies.
How did the actinofibrils come through the skin when the patagium decreased?
ReplyDeleteIt does not have to "come through the skin".
ReplyDeleteJust think about the gene switch being turned off that produces the non-actinofibril part of the membrane. And all that is left then is the thick band of patagium material close to the body with the actinofibrils continuing to extend from it.
Could you please provide a reference link to the scientific literature supporting this?
DeleteI did.
DeleteI don't see any links to any peer reviewed literature. Just a link to an anonymous person's personal blog.
DeleteI suppose this idea can be safely dismissed until such reference links are provided.
Did you check here:

There are a number of references.
Step back for a moment:
Do you now see how the actinofibrils do not "come through the skin". That was your initial question.

Note that the wing feathers of a bird, extend from the thick band of patagium material (called the "postpatagium") close to the body.

The question has been answered by an anonymous blogger's opinion. Not by any scientific literature. Everybody is aware of the nature of opinions.

They provide EVIDENCE for the idea I am presenting.

ReplyDeleteI would be happy for any contribution from others. Care to contribute?
