I noticed you may not have gotten a detailed answer as you may have wanted about the evolutionary origins of the recurrent laryngeal nerve. I think that's because your answer is already in this thread in message 37 and it feels like to most that you haven't bothered to read the thread when you responded to it.
I noticed that there are a number of people that tend to ignore past responses and repeating their questions as if they have nevernever been answered in the first place making threads go round and round which would explain the lack of patience of some members toward those who seem to adopt such an attitude.
