Feather Evolution 3of5

[Frab2001]

LOL...yeah, ok.

[gsmonks]

141 brain-dead creationist shitheads so far. Interesting.

Evolutionists don't bother with creationist shitheads. So why do creationist shitheads bother spamming every documentary on evolution?

Oh, right- they're creationist shitheads. I forgot. Evolution threatens their brain-dead little world, so they try to wipe shit on the facts in order to vandalise the truth.

I applaud the narrator for saying the phrase "where Sonic Hedgehog is turned on" without laughing.

[Mave432]

The whole scientific explanation still does not reflect evolution theory in essence. It's only an explanation of the stages of growth in feathers. The design is still there. The genes are still present. Who created the genes? Calling it Sonic Hedgehog does not explain it is evolution. =/

I am looking to find any truth about evolutionary theory in the next video.

[leananshae]

Ok, so in "Evolution of the Jaw", a scientist, explaining how fish catch prey, said, "Fish suck". Then, in this video, a scientist, describing feathers, says, "Feathers are totally tubular." Surf's up, dude!

So fish suck and feathers are cool!

Evo-Devo!? Sonic Hedgehog?! Some scientists are jargon spin doctors. LOL!

[Rationalific]

Well, "Sonichedgehog" is certainly easier to remember than "BMP2". Obviously, one of them was a gamer who owned a Sega Genesis.

I wonder what environmental change that was present to start the feather evolving chain reaction....maybe flight to avoid land predators....or maybe because some dinosaur mother said," If your friends say "Jump off a cliff, you going to do it?!" The dino kids said "yes"..the mother answers.."well you better grow some wings!!" the dino kid say, "But MOM, you will be the wind beneath my wings!" :P

[devotedpupa]

sonic hedgehog?? suddenly i want to discover something just to name it in an awesome way. i imagine forcing the discovery channel to say " the cheese and mac gene help to..."

[buschmann69]

How come so many people can't think for themselves?? Evolution, especially Macro-Evolution is only believable for monkeys ??!!!

[MatchCard]

I bet i know what game the person who named the gene most likely played on nintendo :p

[evilotakuneko]

Given the timeframe.. he probably played the original on Sega Genesis :p

I have a down blanket and it kept me warm all winter.

[UppruniTegundanna]

1:04 "they're there simply to keep a warm blooded animal warm". I might be being stupid, but didn't he mean "keep a cold blooded animal warm"?

[djarm67]

Birds are warm blooded. Evidence also indicates that many dinosaurs were also warm blooded (endothermic)

[UppruniTegundanna]

Thanks! I was unclear on that point.

[gregrutz]

Don't cold blooded animals produce some heat, they just can't regulate it.

[djarm67]

"Cold blooded" is somewhat of a misnomer. Lizards for example are actually ectothermic in that they gain the majority of body heat from their surroundings. In many cases the body temperature of a lizard will be higher than the normal operating temperature of a warm blooded (endothermic) mammal.

[04carrolld]

no a cold blooded animal needs the sun wihle a warm blood needs its own source of heat in this case feathers trap the heat

[ghazzter]

They called the gene Sonic Hedge Hog.

[TomConger]

Now we just need a good theory as to why/how warm-blooded-ness came about in dinosaurs.

[Nilopollis]

didnt they share a relative of ours in the sail-backs? i was actually just wondering that when i say your comment.

[willowtreephoto]

Same reasons it came about for mammals?

[TomConger]

But do we have a good theory for that? I haven't really studied it too much.

[OceanspiritKeiko]

Wow, very intriguing idea.
