Line 10:
== Examples of poor design ==
Examples of "poor design" cited include:
*
* the urinary tract in the human male, especially the unnecessary passage of the urethra through the prostate gland. As the prostate almost always grows with age, it eventually compresses the urethra and often makes urination difficult or even impossible.
* barely used nerves and muscles (e.g. [[Plantaris muscle]]) that are missing in part of the human population and are routinely harvested as spare parts if needed during operations.
* intricate reproductive devices in [[orchid]]s, apparently constructed from components commonly used for different purposes in other flowers.
Line 18 ⟶ 19:
* the seemingly "backward-facing" arrangement of [[photoreceptor]]s (and the related [[blind spot (anatomy)|blind spot]]s) within the [[retina]]s of many organisms, including all [[mammal]]s.
* portions of DNA — termed [[junk DNA|"junk" DNA]] — that are claimed not to serve any purpose.
*
* the structure of the human [[eye]]. The [[retina]] is "inside out" in that nerves and blood vessels lie on the ''surface'' of the retina instead of behind it as in invertebrate species. Six muscles move the eye when three would suffice. [http://www.2think.org/eye.shtml]
It can be argued that any designer of life was inept or sadistic.
