The recurrent laryngeal nerve is a branch of the vagus nerve which innervates the larynx. But, instead of branching off in the neck and travelling directly to the larynx, for evolutionary reasons it follows a long, looping course down the neck into the thorax, before doubling back on itself to ascend back up the neck to the larynx. This circuitous route is why it's called "recurrent".
As well as being perverse and wasteful, from a "design" point of view, this anatomical arrangement makes the nerve much more vulnerable to injury. In fish, it goes direct.
Compared with a putative designer of life, the Universe, and everything, I'm not very intelligent, but I think even I would have ironed this one out. Did she have a good day with fish, but an off day with mammals?
Answers on a postcard, please.

C'mon guys! Where are all the creation/IDists with their glib explanations of the wisdom behind the circuitous route of this extremely important nerve? It's involved in speech, which is an essential human characteristic. Speech distinguishes we chosen ones from the lower orders, after all ;-)
[Let's not discuss the human appendix, which serves the obvious purpose of making surgeons rich.]

Re: Clutching at Straws
Now for the RLN, do you not think that it's wiring could end up having a positive effect, a function ? It passes right up tight under the aorta, don't you think that all this serves a biological purpose ? I think it in fact will prove to be a very useful feature...
No, and no. The route it takes makes it more vulnerable to injury.
Your thought is "not even wrong".

I never wear sunglasses, do you think I'm going to end up blind ?
It's not unlikely that you'll go blind, but it's very hard to believe you never wear sunglasses.
WTF has this nonsense got to do with the recurrent laryngeal nerve, BTW?

Re: Clutching at Straws
On a final note, I noticed that everybody keeps talking how the ToE explains perfectly well this path by the RLN. I would be interested to here how it explains it. Thanks in advance!
Are you unable to use google?

If not any wiser, then at least you are now better-informed.
