Unintelligent Design

The human body is testament to the absence of determinism in the evolutionary path of animals. And there are several vestigial examples of evolutionary leftovers within the human body. Couple this with the imperfect state of the human eyeball (complete with a blind-spot at the back of the retina), and we have plenty of examples of the way that evolution works. Bodies are not redesigned every time an evolutionary change in a species occurs. Adaptations only hold on if they are advantageous, or at a minimum not harmful to the creature or plant.

The recurrent laryngeal nerve is an odd example of evolution that due to the evolutionary path of mammals takes a much longer journey than it should if evolution were about being efficient then things like this would never happen. Humans seem to be much more like a crammed together mess of spare parts than a divinely designed being.

And there are countless other examples of odd evolutionary quirks. Watch Dawkins’ dissection of a giraffe’s neck to reveal the epic journey of the recurrent laryngeal nerve.
