Can a creationist explain this for me?

A. It functions just fine.
B. There is a reason for it to be that way that we currently do not understand.
C. God did it that way because he did.
D. The Fall did it.

I think I covered all of them....

A 0.51-second Google search yielded this explanation, along with a new term (atheopath), and an example by way of how cars are [poorly?] designed with their engines up front.

Recurrent Laryngeal Nerve

Uh that's why some cars are designed with the engine in the back, or better yet, with the engine in the middle to balance the weight. The path of an exhaust pipe is long because it is carrying waste away from the engine and the driver. A more efficient design is one that you see in hot rods with the pipes coming out near the front of the car on the sides. And why do we see these efficient designs in some cars? Because as designers, we can go back to the drawing board as Dawkins just said int he video. Cars did not evolve through reproduction and inherited traits. A car is made and driven and the designer can see the flaws and make corrections on the next model. The next Camaro can have nothing what-so-ever to do with the model before it.

Recurrent Laryngeal Nerve

Also from the article:

"Dawkins considers only its main destination, the larynx. In reality, the nerve also has a role in supplying parts of the heart, windpipe muscles and mucous membranes, and the esophagus, which could explain its route."

 

[DontTreadOnMike]

It's still incredibly inefficient. Why not have it branch right at the opening where it comes out of the brain? Why not have a branch that goes directly to all of the different organs?

Here we go.

Why not have Dawkins explain it to you -- once you convince him he's wrong?

After all, if it was Dawkins that convinced you this nerve is 'inefficient', perhaps Dawkins could show you otherwise?

 

[DontTreadOnMike]

Here we go.

Am I supposed to know what that is? A soccer goal? Oh wait are you trying to be clever and say that I'm moving the goal posts? My initial argument was that it was inefficient. And now my argument is....that it's inefficient. Nice try though.

Just like a creationist to focus on who the message is coming from rather than what the message is. I didn't hear it from Dawkins, but no one else made a video of a giraffe being dissected, so he was the one who got posted. Why would I convince him that he's wrong? You have yet to convince ME that he's wrong.

*buzzer*. Wrong. The anatomy of the vagus nerve says otherwise. The vagus nerve travels from the cranium and down towards the trachea then to the heart. The heart branches come off the bits of nerve heading south. The recurrent laryngeal nerve does not innervate the lungs or the heart, but purely the larynx. The fact that it curls under the aortic arch on the left and the subclavian artery on the right is completely pointless. There is no reason for the nerve to travel that way for us (and less reason in giraffes!)

(And I double-checked this in my atlas of anatomy just now)

Oh snap. I was about to submit this to reddit/r/atheism for him since Dawkins is probably too busy lambasting the pope right now. I guess there's no need anymore.

I would like to see literature on the functions it plays in the heart and body. I have a strong suspicion the this is just one of the lies that creationists tell because all of the literature I've read only discuss laryngeal problems associated with damage to the nerve. Your source only links to an anatomy site discussing only the anatomy of the nerve. I want to see the physiological role it plays in the heart because to the best of my knowledge it doesn't play one. It would be very dishonest of those creationists to make physiological claims if the is no literature to support those claims.

As I stated in my post, the recurrent laryngeal nerve only supplies the larynx with innervation. It branches off of the vagus nerve, which continues caudally to innervate the heart. The recurrent laryngeal nerve has no other branches, and no reason to travel caudally to loop around the major blood vessels.

The only reason it gives off some minor nerve filaments in these areas is because of the circulous path it takes. These filaments are hardly the main purpose of the nerve's route and even if they were it would still be grossly inefficient anyway.

Dont you find it interesting? God aside, the giraffe evolves as is all on its own. The RLN has a route seemingly unnecessary. Lets forget about that for a minute and focus on some other facts about the giraffe.I picked these up on the internet which anyone can find by typing in 'facts on giraffes'.


1)The blood vessels in their necks contain one way valves which prevent them from choking and, they have seven vertebrae, the same as humans. Anchor muscles on the giraffe's shoulders, however, help to prop up the neck.
2)A giraffe's front legs are about 10 percent longer than the back legs.
3)At an average 8 feet, giraffes' tails are some of the longest in the animal kingdom.
4)At the end of the tail is a bunch of stiff, black hair.
5)One of the fascinating giraffe facts is that these animals have antiseptic saliva which helps thorn-inflicted wounds on the tongue to heal fast.
6)The giraffe cow delivers a single calf while standing. The calf, which falls out onto the ground (about 6 to 8 feet) is usually breastfeeding in an hour and running around in a couple of hours.
7)At birth, a calf is already 6 feet tall, taller than the average human being.
8)Another interesting giraffe fact is that giraffes sleeps standing up for between 20 minutes to 2 hours a day.
9)A giraffe consumes about 140 pounds of foliage a day. Like cattle, giraffes are ruminants with 4-chamber stomachs. They therefore re-chew their food several times, a process known as "chewing the curd."
10)Each coat of the giraffe is different, like the fingerprints of people.
11)Each step they take is usually fifteen feet in length and they can run up to thirty-seven miles per hour.
12)A giraffe has a large heart that weights about 22 lbs and measures about 2 feet.
13)Their heart rate is about one-hundred seventy beats per minute, pumping approximately sixteen gallons of blood per minute!
14)Giraffes have high blood pressure (240/160) for pumping blood to the brain. The carotid artery that carries blood from the heart to the head is thick, muscular and elastic, ballooning when the giraffe stoops to absorb increase in pressure. When the giraffe raises its head, a series of check valves in the inch-wide jugular vein prevents a sudden back flow from the emptying brain.


Number 14, about the blood pressure, check valves and so on is what I find especially interesting. Evolution can perform this task gradually, or the giraffe certainly would not be around. But it screws up on the RLN. Go figure?

The video explains why the nerve is screwed up on the giraffe and on all mammals.

Thanks for posting this wonderful testament to natural selection, for without these adaptations, there would be no giraffe.

I've yet to see any evidence to the contrary. Until then, I'll accept what can be observed and confirmed via scientific method. No amount of spamming this nonsense will change my opinion. "A" for effort though.

Fun Fact:

People who suffer severe cervical acceleration/deceleration (aka whiplash) will sometimes present with a 'hoarse,' raspy voice, due to the fact that the RLN has been stretched and injured.
