Wing evolution 3of4

[Ceilaus]

This is a great video i love learning about the evolution of things, i just want to know now how certain genomes are activated or created to give a certain species their ability fly or other physical advantages to help them survive. if anyone has a link to such research i would love to learn =)

Evolution rulez!!!!

[Siddis33]

I have a problem with this flight developing theory from running uphill. In order for an animal to start flapping their ill adapted forelimbs to aid climbing they'd have to give up any other function of their forelimbs and claws, like climbing with them.

[stupidtrooper501]

@Siddis33 its safe to say that if they evolved wings then they most likely could not use their arms to climb

[4alexza]

They theory doesn't make sense. If I was a bowler and after YEARS of bowling my bowling arm SOMEHOW became longer than my other one because my body saw a need to "adapt" that. My children would not have long bowling arms and thus what they are suggesting could NOT have happened. It is ludicrous in the highest degree.

[DutchNordic]

@4alexza imagine a whole group of people that bowl to make a living. In this group there will be natural (genetic) variation. Some people will have slightly longer arms then others. Over many generations the genes for longer arms will be slightly in the advantage because they help the bowler to make a living. Now its only a matter of time before longer arms will come to dominate the population.

@4alexza Individuals do not evolve, populations do.

This is a really good one. Thanks, djarm67.

It was so interesting to learn about this theory for how flight may have evolved in birds. I've always wondered about the possible intermediate stages.

I wish, though, that the video had gone into at least some detail about how insect wings may have evolved. I suppose it could have started with mutations that allowed certain insects to glide briefly while jumping from one tree to another, or something like that.

Cool cool stuff!

[Bobbiethejean]

UG! These documentaries are always so badly worded. Anti-evolutionist morons eat this shit for breakfast. "Why did birds *want* to fly." "Wings *suddenly* appeared in the fossil record."

Most of us who aren't idiots know what the narrator means but dumb people seize on such miswordings and use them to bolster their case against evolution.

[luker4459]

Yeah i know... It is annoying.

[SanRafaelSwell]

I am in full agreement. They should hire EDUCATED writers.

[yogurtmantotherescue]

creation vs evolution.....

evolution wins(big time).

[waltermh111]

I think the reason they still use their feet because its still quicker then trying to just fly up.

Its logical to use 2 energy creation devices for faster access, then just to use wings and waste the use of their legs.

Its definitely more beneficial to an animal to get places faster, when running away or running after something.

[sheepwshotguns]

if walking on inclines was the primary reason for the evolution of the birds wing, wouldn't stronger legs or sticky feet be a more economical adaptation for attaining the same goal?

[zahir13]

Perhaps, but evolution doesn't result in the best possible adaptation. Rather it results in the best adaptation that happens to occur. An analogy would be that each poker hand ends with the best available "hand" rather than the best possible one (i.e. a royal straight flush in spades).

[IbeeejayI]

The wings were already there, it would be easier to improve an existing structures. Leg strength doesn't increase the angle that you can walk up and sticky feet is a drastic change

[Gerafix]

Perhaps they realize that it takes more energy to fly up the ramp and therefore would rather just walk since it takes less energy. This experiment seems questionable to me.

[MrFacet]

gerafix they did mention that in the end the walking and flapping takes the same energy as flying. They are quite advanced in calculating that.

My own objection would be that the bird may see that the space above it is limited. But often such questions are considered in the original article. And this is a documentary aimed at lay people.

[devil238]

Great documentary but.... THAT'S NOT HOW YOU PRONOUNCE NICHE BIRDMAN.

[willowtreephoto]

depends on where you live

[Paxmax]

gah! cliff hanger!

[misslipstickvogue]

This is such a wonderful series, you can tell that creatiobots are having a lonely thursday night. pathetic.

Thanks for sharing

[TheKingOfFresno]

The creatards are on this already? Five bucks says they don't even watch or listen to the information the vids have to offer, they just downvote and move on. Cowards.

[Teirusu155]

low rating countered! Who does this crap? I can't stand such disrespect
