Editing Argument from poor design

{{Short description|Argument against assuming the existence of God}}
{{Atheism sidebar |arguments}}

The '''argument from poor design''', also known as the '''dysteleological argument''', is an argument against the assumption of the [[Existence of God|existence of]] a [[Creator deity|creator]] [[God]], based on the reasoning that any [[omnipotence|omnipotent]] and  [[omnibenevolence|omnibenevolent]] [[deity]] or deities would not create [[organism]]s with the perceived suboptimal designs that occur in nature.

The argument is structured as a basic ''[[modus ponens]]'': if "creation" contains many defects, then design appears an implausible theory for the origin of earthly existence.  Proponents most commonly use the argument in a weaker way, however:  not with the aim of disproving the existence of God, but rather as a ''[[reductio ad absurdum]]'' of the well-known [[teleological argument|argument from design]] (which suggests that [[biology|living things]] appear too well-designed to have originated by chance, and so an intelligent God or gods must have deliberately created them).

Although the phrase "argument from poor design" has seen little use, this type of argument has been advanced many times using words and phrases such as "poor design", "suboptimal design", "unintelligent design" or [[Dysteleology|"dysteleology/dysteleological"]]. The nineteenth-century biologist [[Ernst Haeckel]] applied the term "dysteleology" to the implications of organs so rudimentary as to be useless to the life of an organism.<ref name="haeckel">{{cite book |first= Ernst |last= Haeckel |author-link= Ernst Haeckel |year= 1892 |url= https://archive.org/details/historycreation01schmgoog |title= The History of Creation |publisher= D. Appleton |location= Appleton, New York |page= [https://archive.org/details/historycreation01schmgoog/page/n359 331]}}</ref>  In his 1868 book ''Natürliche Schöpfungsgeschichte'' (''The History of Creation''), Haeckel devoted most of a chapter to the argument, ending with the proposition (perhaps with tongue slightly in cheek) of "a theory of the ''unsuitability of parts'' in organisms, as a counter-hypothesis to the old popular doctrine of the ''suitability of parts''".<ref name="haeckel"/>  In 2005, Donald Wise of the [[University of Massachusetts Amherst]] popularised the term "incompetent design" (a play on "[[intelligent design]]"), to describe aspects of nature seen as flawed in design.<ref>{{cite journal |last=Wise |first=Donald |date=2005-07-22 |title="Intelligent" Design versus Evolution |journal=Science |publisher=[[American Association for the Advancement of Science|AAAS]] |volume=309 |issue=5734 |pages=556–557 |doi=10.1126/science.309.5734.556c |pmid=16040688|s2cid=5241402 }}</ref>

Traditional Christian theological responses generally posit that God constructed a perfect universe but that humanity's misuse of its [[free will]] to [[Fall of man|rebel against God]]<!--[?:], and the consequent damage from hostile spiritual forces,--> has resulted in the corruption of divine good design.<ref>Harry Hahne, [https://books.google.com/books?id=K-Ls4CUEWFAC&dq=Creation+fallen+due+to+sin&pg=PA211 ''The Corruption and Redemption of Creation: Nature in Romans 8, Volume 34'']</ref><ref>Gregory A.

Charles Taliaferro, Chad Meister, ''The Cambridge Companion to Christian Philosophical Theology'', [https://books.google.com/books?id=KJQyhzY4PucC&dq=augustine+privation+of+good+fallen+creation&pg=PA160 pages 160-161] - "Fundamental to the position is Augustine's view that the universe God created is good; everything in the universe is good and has good purpose [...]. [...] How did evil arise? It came about, he maintains, through free will. [...] some of God's free creatures turned their will from God, the supreme Good, to lesser goods. [...] It happened first with the angels and then [...] with humans. This is how moral evil entered the universe and this moral fall, or ''sin'', also brought with it tragic cosmic consequences, for it ushered in natural evil as well."

== Overview ==
[[File:Fitness-landscape-cartoon.png|thumb|right|Natural selection is expected to push fitness to a peak, but that peak often is not the highest.]]

The argument runs that:

# An [[Omnipotence|omnipotent]], [[Omniscience|omniscient]], [[Omnibenevolence|omnibenevolent]] creator God would create organisms that have optimal design.
# Organisms have features that are suboptimal.
# Therefore, God either did not create these organisms or is not omnipotent, omniscient and omnibenevolent.

It is sometimes used as a [[reductio ad absurdum]] of the well-known [[Teleological argument|argument from design]], which runs as follows:

# Living things are too well-designed to have originated by chance.
# Therefore, life must have been created by an intelligent creator.
# This creator is God.

"Poor design" is consistent with the predictions of the [[scientific theory]] of [[evolution]] by means of [[natural selection]]. This predicts that features that were evolved for certain uses are then reused or co-opted for different uses, or abandoned altogether; and that suboptimal state is due to the inability of the [[heredity|hereditary]] mechanism to eliminate the particular vestiges of the evolutionary process.

In [[fitness landscape]] terms, natural selection will always push "up the hill", but a species cannot normally get from a lower peak to a higher peak without first going through a valley.

The argument from poor design is one of the arguments that was used by [[Charles Darwin]];<ref>[[Charles Darwin|Darwin, Charles]]. ''[[The Origin of Species]]'', 6th ed., Ch. 14.</ref> modern proponents have included [[Stephen Jay Gould]], [[Richard Dawkins]], and [[Nathan H. Lents]]. They argue that such features can be explained as a consequence of the gradual, cumulative nature of the evolutionary process. [[Theistic evolutionists]] generally reject the argument from design, but do still maintain belief in the existence of God.{{citation needed|date=January 2017}}

American scientist [[Nathan H. Lents]] published his book on poor design in the human body and genome in 2018 titled ''Human Errors''. The book ignited a firestorm of criticism from the creationist community<ref>{{Cite web |title=Creation: Review of Human Errors by Nathan H Lents |url=https://creation.com/review-human-errors-nathan-lents}}</ref><ref>{{Cite web |title=Evolution News: articles about Human Errors |url=https://evolutionnews.org/?s=%22human+errors%22}}</ref> but was well received by the scientific community and received unanimously favorable reviews<ref>{{Cite web |title=Human Errors: The Human Evolution Blog |date=16 October 2017 |url=https://thehumanevolutionblog.com/book-human-errors/}}</ref> in the dozens of non-creationist media outlets that covered it.

Several defects in human anatomy can result in death, especially without modern medical care:
* In the human female, a [[zygote|fertilized egg]] can implant into the [[fallopian tube]], [[cervix]] or [[ovary]] rather than the [[uterus]] causing an [[ectopic pregnancy]]. The existence of a cavity between the ovary and the fallopian tube could indicate a flawed design in the female reproductive system. Prior to modern surgery, ectopic pregnancy invariably caused the deaths of both mother and baby. Even in modern times, in almost all cases the pregnancy must be aborted to save the life of the mother.
* In the human female, the [[vagina|birth canal]] passes through the [[human pelvis|pelvis]]. The prenatal skull will deform to a surprising extent. However, if the baby's head is significantly larger than the pelvic opening, the baby cannot be born naturally. Prior to the development of modern surgery ([[caesarean section]]), such a complication would lead to the death of the mother, the baby, or both. Other birthing complications such as [[breech birth]] are worsened by this position of the birth canal.
* In the human male, [[testes]] develop initially within the [[abdomen]]. Later during gestation, they migrate through the abdominal wall into the [[scrotum]]. This causes two weak points in the abdominal wall where [[hernia]]s can later form. Prior to modern surgical techniques, complications from hernias, such as intestinal blockage and [[gangrene]], usually resulted in death.<ref name="Jury">{{cite web |first=Chris |last=Colby |author2=Loren Petrich |year=1993 |url=http://www.talkorigins.org/faqs/jury-rigged.html |title=Evidence for Jury-Rigged Design in Nature |publisher=[[Talk.Origins]] |url-status=live |archive-url=https://web.archive.org/web/20110811235247/http://www.talkorigins.org/faqs/jury-rigged.html |archive-date=2011-08-11 }}</ref>
* The existence of the [[pharynx]], a passage used for both [[ingestion]] and [[respiration (physiology)|respiration]], with the consequent drastic increase in the risk of [[choking]].

Furthermore, at high altitudes, oxygen deprivation can occur in unadapted individuals who do not consciously increase their breathing rate.

==As an argument regarding God==
The argument from poor design is sometimes interpreted, by the argumenter or the listener, as an [[argument against the existence of God]], or against characteristics commonly attributed to a [[creator deity]], such as [[omnipotence]], [[omniscience]], or personality. In a weaker form, it is used as an argument for the incompetence of God. The existence of "poor design" (as well as the perceived prodigious "wastefulness" of the evolutionary process) would seem to imply a "poor" designer, or a "blind" designer, or no designer at all. In Gould's words, "If God had designed a beautiful machine to reflect his wisdom and power, surely he would not have used a collection of parts generally fashioned for other purposes. Orchids are not made by an ideal engineer; they are jury-rigged...."<ref>{{cite web |url=http://www.stephenjaygould.org/library/gould_panda%27s-thumb.html |title=The Panda's Peculiar Thumb |work=NATURAL HISTORY |date=November 1978 |url-status=live |archive-url=https://web.archive.org/web/20060928063454/http://www.stephenjaygould.org/library/gould_panda's-thumb.html |archive-date=2006-09-28 }}</ref>

The apparently suboptimal design of organisms has also been used by proponents of [[theistic evolution]] to argue in favour of a creator deity who uses [[natural selection]] as a mechanism of his creation.<ref>[[Francis Collins|Collins, Francis S.]] ''The Language of God'' (New York: Simon & Schuster), 2006. p 191. {{ISBN|978-1-4165-4274-2}}</ref> Arguers from poor design regard counter-arguments as a [[false dilemma]], imposing that either a creator deity designed life on earth well or flaws in design indicate the life is not designed. This allows proponents of [[intelligent design]] to [[Cherry picking (fallacy)|cherry pick]] which aspects of life constitute design, leading to the [[unfalsifiability]] of the theory. Christian proponents of both intelligent design and creationism may claim that good design indicates the creative intelligence of their God, while poor design indicates corruption of the world as a result of [[Alvin Plantinga's free will defense|free will]] that caused the [[fall of man]] (for example, in [[Book of Genesis|Genesis]] 3:16 [[Yahweh]] says to [[Eve]] "I will increase your trouble in pregnancy").<ref>{{cite web |url=https://answersingenesis.org/human-evolution/the-evolution-of-childbirth/ |title=The Evolution of Childbirth? |last=Mitchell |first=Dr. Elizabeth |date=15 November 2006 |website=Answers in Genesis |access-date=11 December 2020}}</ref>
