# The extraordinarily long neck of the [[giraffe]]. The giraffe's heart creates immense pressure to drive blood up the neck to the brain. Because of this there are valves in the neck which automatically restrict the blood flow when the giraffe lowers its head to drink. Without these valves the sudden increase in blood pressure as the heart no longer needs to overcome gravity would rupture the arteries in the brain and kill the giraffe. However the giraffe could not have evolved a long neck without the valves and had no need to evolve the valves unless it had a long neck. The okapi, which evolutionists claim is the closest relative of the giraffe, has no such valves. Evolutionary theory cannot explain this. <ref>[http://www1.pacific.edu/~e-buhals/GIRAFFE2.htm]</ref>[[Image:BacterialFlagellum.jpg|thumb|200px|right|[[flagellum|Bacterial Flagellum]] with rotary motor, courtesy of Access Research Network (Art Battson)]] | # The extraordinarily long neck of the [[giraffe]].
