actually the ones you was talking about was all birds not dinosaurs. according to your text books of most of the 90s dinosaurs had no feathers. you cant add them later to suit evolution. the ones on your videos are clearly birds. not reptiles. scales cannot grow feathers.thank you.

Actually my friend, feathers are specialized scales. This is widely known and accepted.

Actually, that isn't a bad idea... I will have to do research, though I'm sure the rest of BLS knows more about the subject than myself.

Stay tuned (subscribe) and keep a look out for that video if we end up making it.

We didn't add feathers later. we discovered fossilized feather impressions so we updated the image to match the reality. Also, morphologically, feathers and scales are essentially the same thing. Just like the hair on your head and a Rhinos horn are very similar.

No a magical floating man in the sky made them all in their complete form lol.

Respond to this video... Dinosaurs. This could be a genetic throw back to ancestral species as the genes are still present, just no switched on so to speak. The claws help the young to climb in the trees that they nest in and are useful in various survival techniques they employ to escape predators. Read about them on wikipedia if you want to learn more. This is an amazing subject!

@Youllhaveat It is widely accepted birds evolved from the dinosaurs. If you are unfamiliar with the fossil 'Archaeopteryx' you should definitely have a look. It shows an intermediate between birds and dinosaurs. Archaeopteryx has distinct feathers, hollow bones but has a more reptilian jaw with teeth. Another interesting bird alive today is the Hoatzin, a bird that lives in South America and its young have actually got claws on their wings that helps to support the evolution of birds from

@mrlollypoppy When you say that they are added later, it is not to suit evolution. It is simply a gap in the knowledge that has since been filled in support of evolution. Every single day there is more knowledge gained that supports evolution. To ad to this, most birds still have scales of some sort too. Look at their legs, they have scales. Hens are a good example of this.

Only just found this, great vid! I found an article in a scientific journal which described the genes for making beta-Keratin, the feather protein, had been found in modern crocodilians, but is now dormant. This means that a major group of archosaurs had developed a insulated covering well before the emergence of dinosaurs. This explains the later development of feathers as well as the curious "bustles" of heterodontosaurids.

@Belikescopes lol pwnt

@megahawk46 They still can use feathers as 'hanglider'. Some chickens actually 'jump' from one building roof to another. But since their body became too fat and wings became too small, actual 'flight' is impossible :/

[megahawk46]

why cant chickens fly again???

@mrlollypoppy yea nice job trying to correct the man. hes right on this one
