Feather Evolution 5of5

Whilst the traditional view on the evolution of feathers was in relation to flight, new discoveries of feathered dinosaurs in China have changed this to focus on thermoregulation and display. Similarly, the evolutionary path from reptilian scales to bird feather has been turned on its head by tubular structures from the follicle.

Certain organisations continue to parrot the phrase "no transitional fossils have ever been found". However, the list of species which possess transitional features continues to grow.

Epidexipteryx hui, Protoavis, Protarchaeopteryx, Archeopteryx, Avimimus, Sinosauropteryx, Caudipteryx, Rahonavis, Shuvuuia, Sinornithosaurus, Beipiasaurus, Microraptor, Nomingia, Epidendrosaurus, Cryptovolans, Scansoriopteryx, Yixianosaurus, Dilong, Pedopenna, Jinfengopteryx, Sinocalliopteryx, Sinornis, Ambiortus, Hesperornis, Ichthyornis

i just sprang an idea, where does the terradactyl fit into all of this, if it does at all?

Anyways, it was an informative watch.

(Take that creationists)!!

Pterodactyls were a type of pterosaur. These flying reptiles shared a similar archosaur heritage to dinosaurs but were not dinosaurs themselves. Birds are not descendents of pterosaurs.

T-rex had feathers? Phenomenal!

[djarm67]

T-rex itself didn't have feathers. However, a smaller Tyrannosaur species Dilong, had primitive feather-like structures.

No, there are THREE views on how flight developed:

1. Tree climbing dinosaurs which glided

2. Fast runners which jumped short distances

3. Magic man did it

That was amazing! Knowledge moves forward, at a pace almost impossible to stay up with.

Why is it that on so many of these evolution documentaries a theist vs. atheist debate breaks out? Evolution has nothing to do with theism or atheism, you morons.

@Mave432 Evolution is not a "belief". It's how things work. No "divine" b.s. required.

[Mave432]

@Keinlicht Environmental stress can be caused by human or a natural intervention such as pollution, etc. but who designed the way animals/humans evolve in response to the stress? In case of computer simulation the divine power for that computer is human but compared to the complexities in natural evolution, it is still exponentially simplistic and imperfect.

Also it still doesn't answer where did such a thing as a feather come from on a raptor at the first place?

[Keinlicht]

@Mave432 So then how come "Divine power" is indistinguishable from selective allele variation in populations undergoing environmental stress? Is there "Divine power" in computer simulations of reproduction with variation?

[KKSCJR]

This just excelled my desire to be an Ornithologist... EVEN MORE!

@Mave432

Wow, well this "devine power" is a sadistic bastard

[KadoatieXD]

Even tho I already learned ALL this in wikipedia (and some more) I still wanted 2 watch this program for it's different point of views :D

[USERNAMEfieldempty]

Why is the narrator talking like i'm an ADHD six year old?

[Mave432]

Also who put feathers on the Raptors? lol no answer.

[Mave432]

I believe in evolution but natural selection is not a phenomenon that happens automatically. It's a Devine power that guides the nature to make the selections.
