Mailvox: atheist biology

Richard Dawkins’s logic is not only flawed, but as Warkicker, an accomplished surgeon, notes, his grasp of animal and human biology is also nonexistent.

MORE ATHEIST LOGIC: You can trust atheists. Because evolutionary biologists don’t understand how biological functions work.

What a curious argument Dawkins gives regarding the “poor design” of the recurrent laryngeal nerve. Is he not aware that the nerve does more than innervate the larynx? It gives branches to the cardiac plexus, esophagus and trachea in addition to the muscles of the larynx. Hence its circuitous route is necessary and not inefficient. I do thyroidectomies all the time and have to be careful not to injure any part of the nerve during the dissection, not just the branches that serve the larynx. Also, the superior laryngeal nerve does give a direct connection to the larynx, and complements the recurrent laryngeal nerve and provides redundancy in function, so a more direct pathway already exists.

There are unusual conditions in which either the right or left recurrent laryngeal nerves do not loop around in the chest but rather directly innervate the larynx. In such individuals, there is the potential for significant problems in swallowing and breathing. Ironically, if you subscribe to the evolutionary paradigm, such conditions may represent example of mutations that regularly occur but yet evolution “chooses” not to select out for the more direct route!

Additionally, the long route the recurrent laryngeal nerve takes into the thoracic cavity before looping back up to the neck may have saved the lives of many of my patients. They will present with hoarseness prompting me to look at their vocal cords. If I see paralysis of one of the vocal cords, I evaluate their chest and often with find a tumor in their mediastinum, usually early enough to still be treatable. Dr. Michael Egnor, a well-known neurosurgeon, has noticed and commented on this as well.
