paused at :01 staring at the womens.
Hit play and :awesome:
Good video though
Neat stuff.
richard dawkins gives atheists a bad name.
I'm seriously wondering what the hell could've caused that to happen

Please, don't

Didn't you watch all of the video?
That was interesting, I found it weird that it didn't bleed at all though.

There is blood, but there's nothing pumping it as it's dead, so why are you surprised?

It was the most direct route in fish. But since then, we've grown necks, and the nerve hasn't been rewired. They explain right at the end.

When the heart isn't beating, and consequently the blood isn't flowing, then little blood leaks out. There'd be far more if the giraffe were still alive.

Evolution works gradually. Rerouting the nerve to a more optimum path is too big a gap to leap, so instead it just gets longer, which is much easier to do.

God is obviously a drunken asshole.

It's not really a matter of 'ease' or a 'big gap'. You [I]could[/I] have a mutation that didn't reroute the nerve like that, and made it more direct. But then the environment would have to benefit (in terms of mating) that giraffe because of the mutation, and then it would need to make a lot of babies while the environment still benefited that build more than those without the mutation.
You're on the right track though, a faster response time to the larynx wouldn't benefit giraffes, so I doubt it's ever going to get shorter.

I did, and I know that evolution is a slow process, but why couldn't it have been rewired? Or at least not wrapped around an artery?
Reminded me of this [media]http://www.youtube.com/watch?v=C7HCIGFdBt8[/media]
This is really interesting. It makes you think what used to go there to warrant that kind of uselessness in a nerve.

Regular cool posts. Please pay no mind.
Why did I imagine it coming to life
That's actually extremely interesting.

It could have been rewired, for all we know. There's no reason why not. But I suspect the advantage would be insignificant, probably so insignificant that it'd have very little influence on an animal's chances of survival, and consequently, have little to no effect on the survival of the gene which rewired this nerve.
