Question

Hey, as per darwin everything evolved. So did the birds feathers evolve?

Answer 1

Never really read Darwin, have you? You're not alone. You would be amazed at the number of things that are attributed to Darwin that he never said. I would suggest that you actually read what he wrote. Pay particular attention to what Darwin says is the CAUSE of the changes that occur.

Answer 2

@Jim the Baptist, the Ice Age didn't wipe out the dinosaurs. They died out millions of years before the Ice Age. And the first birds evolved long before the dinosaurs died out.



The fossil record shows the evolution of birds from small, feathered theropod dinosaurs.



Why do creationists keep thinking that they can disprove something they are abysmally ignorant about?



Added:



There are a great many fossils of small dinosaurs with feather impressions showing a wide variety of forms.

Archaeopteryx lived around 150 million years ago. By the the time of the demise of the dinosaurs 65 million years ago, modern type birds had evolved, but no present day species of birds existed at that time.



Here is one of the many fossils of archaeopteryx. There are distinct impressions of flight feathers.

The first link below is to a reconstruction of the archaeopteryx skeleton. The next link is to the skeleton of a modern bird. The archaeopteryx skeleton shows the beginning of the evolution to birds from a theropod dinosaur, which is also shown in the third link.

Whoa! Thumbs down, by haters of reality, to my answer and others that provided evidence of the evolution of birds from small, feathered dinosaurs.

Answer 3

Yes. Feather evolution can be traced back to scales. You do know that some theropod dinosaurs had feathers, right? For example, velociraptor is known to have been feathered, and it is thought that juvenile tyrannosaurs also had feathers. The theropod lineage gave rise to the ancestors of modern birds.



Feathers probably evolved for thermoregulation - they kept the dinosaur warm. They may also have played a secondary role in sexual selection, like the plumage of modern birds. Later, in modified forms, they were co-opted as a structure for flight (or not, in the case of ratites).

Answer 4

Yep ! Sure did and there are quite a few transitional fossils to prove this happened.



If you are in any doubt look at the legs and feet of the Australian emu



The legs are covered in scaly skin and the feet and claws are almost identical to those found on many dinosaurs.



Feathers evolved from scales to provide warmth then flight.

Answer 5

There is evidence for feathers evolving from scales with homology between the keratin and between the embryogenetic path.

“A comparison of genomic coding sequences for feather and keratins: structural and evolutionary implications” Feather-like keratin genes may have evolved from a scale keratin gene by a single deletion event. http://docs.google.com/viewer?a=v&q=cache:JbIoXHdU0BAJ:www.ncbi.nlm.nih.gov/pmc/articles/PMC557315/pdf/emboj00305-0167.pdf+feather+scale+homology&hl=en&gl=us&pid=bl&srcid=ADGEESi0XMO9b1Atuq1-zrvpvAoSWSRPvooEV6Mjrx08dsn1fVydRcOwwdDVPXpoVMTNLTvEkj0tC97QZOKTIkBM6c7p2gg86EAYhzJXufxfoniBJ9oD8Vtvd8tWnkqhWVSzsECHN3d-&sig=AHIEtbQ9N_al82ALfEkqYZGBxHi4kcWNzw

Feathers and scales also share developmental homology. Both first appear as tissue swellings called placodes, under the control of similar genes. From there the regulatory steps diverge so the developing structures diverge.

The basic first step in scale development was retained, but later steps were altered or replaced with a new series of developmental events specific to feathers. Feather geneticss may be orthologs of scales or gene duplication paralogs of the primitive developmental machinery that was used to build scales in a novel feather path.

Answer 6

Well, birds evolved to have feathers.

Answer 7

Yup

Answer 8

Of course.



And to Chris who thinks dinosaurs didn't have feathers....

Answer 9

What does this have to do with the Religion and Spirituality section?

Answer 10

Evolutionist will tell you that the chicken in your back yard used to be a T-rex



But where are the billions and billions of fossils that should be present that link the two together?

And if an ice age wiped out dinosaurs, why do we have so many birds?



God created birds on the 6th day of the creation week back in Genesis 1

Answer 11

they most certainly did. birds are often linked to dinosaurs. and we know that dinosaurs didn't have feathers.

Answer 12

Yes



http://www.talkorigins.org/faqs/feathers.html



that explains it

Answer 13

That's the Idea.

Answer 14

Yes. See biology textbooks or the Internet for an explanation.
