This. Another example is the recurrent laryngeal nerve.

  >The extreme detour of the recurrent laryngeal nerves, about 4.6 metres (15 ft) in the case of giraffes, is cited as evidence of evolution, as opposed to intelligent design. The nerve's route would have been direct in the fish-like ancestors of modern tetrapods, traveling from the brain, past the heart, to the gills (as it does in modern fish). Over the course of evolution, as the neck extended and the heart became lower in the body, the laryngeal nerve was caught on the wrong side of the heart. Natural selection gradually lengthened the nerve by tiny increments to accommodate, resulting in the circuitous route now observed. https://en.wikipedia.org/wiki/Recurrent_laryngeal_nerve#Evidence_of_evolution https://en.wikipedia.org/wiki/Recurrent_laryngeal_nerve#Evid...
