Ontogenetic depth is a pseudoscientific idea proposed in February 2003 by Paul Nelson, an American philosopher of science, young Earth creationist and intelligent design advocate; [1] he is employed by the Discovery Institute.
Basically, Nelson concludes in his 'hypothesis' that developmental complexity is infrangible, and that if he shows Cambrian organisms to be complex, then it is therefore impossible for them to have evolved. [2] [3] Nelson proposes 'ontogenetic depth' as evidence of specified complexity, and a reliable marker of design by an intelligent agent, in opposition to modern evolutionary theory.
Nelson subsequently stated that ontogenetic depth is "Currently Impossible to Measure". [4]
Biologist PZ Myers, who works in the field of evolutionary developmental biology, dismissed the concept, stating in 2010 that "Nelson is a creationist who made up this wacky claim of "ontogenetic depth", saying he had a way of objectively measuring the complexity of the developmental process in organisms with a number that described the distance from egg to adult. Unfortunately, he forgot to tell us how one calculated this number, or how it actually accounted for the complexity of a network, or even how we'd get a number that was different for a sponge and a cat. But he did say he'd get back to us with the details tomorrow...six years ago." [5] Myers concludes that "ontogenetic depth is a sloppily-defined concept with no theoretical support for its validity and no apparent operational utility." [6]
The concept of 'ontogenetic depth' has not been published in any peer-reviewed journal, there are no methods described that would allow to measure this value in any organisms, nobody other than Nelson and his collaborator, Marcus Ross, do anything with the idea. [5]
Intelligent design (ID) is a pseudoscientific argument for the existence of God, presented by its proponents as "an evidence-based scientific theory about life's origins". Proponents claim that "certain features of the universe and of living things are best explained by an intelligent cause, not an undirected process such as natural selection." ID is a form of creationism that lacks empirical support and offers no testable or tenable hypotheses, and is therefore not science. The leading proponents of ID are associated with the Discovery Institute, a Christian, politically conservative think tank based in the United States.
Irreducible complexity (IC) is the argument that certain biological systems with multiple interacting parts would not function if one of the parts were removed, so supposedly could not have evolved by successive small modifications from earlier less complex systems through natural selection, which would need all intermediate precursor systems to have been fully functional. This negative argument is then complemented by the claim that the only alternative explanation is a "purposeful arrangement of parts" inferring design by an intelligent agent. Irreducible complexity has become central to the creationist concept of intelligent design (ID), but the concept of irreducible complexity has been rejected by the scientific community, which regards intelligent design as pseudoscience. Irreducible complexity and specified complexity, are the two main arguments used by intelligent-design proponents to support their version of the theological argument from design.
William Albert Dembski is an American mathematician, philosopher and theologian. He was a proponent of intelligent design (ID) pseudoscience, specifically the concept of specified complexity, and was a senior fellow of the Discovery Institute's Center for Science and Culture (CSC). On September 23, 2016, he officially retired from intelligent design, resigning all his "formal associations with the ID community, including [his] Discovery Institute fellowship of 20 years". A February 2021 interview in the CSC's blog Evolution News announced "his return to the intelligent design arena".
The Blind Watchmaker: Why the Evidence of Evolution Reveals a Universe without Design is a 1986 book by Richard Dawkins, in which the author presents an explanation of, and argument for, the theory of evolution by means of natural selection. He also presents arguments to refute certain criticisms made on his first book, The Selfish Gene. An unabridged audiobook edition was released in 2011, narrated by Richard Dawkins and Lalla Ward.
Icons of Evolution is a book by Jonathan Wells, an advocate of the scientific intelligent design argument for the existence of God and fellow of the Discovery Institute, in which Wells criticizes the paradigm of evolution by attacking how it is taught. The book includes a 2002 video companion. In 2000, Wells summarized the book's contents in an article in the American Spectator. Several of the scientists whose work is sourced in the book have written rebuttals to Wells, stating that they were quoted out of context, that their work has been misrepresented, or that it does not imply Wells's conclusions.
Specified complexity is a creationist argument introduced by William Dembski, used by advocates to promote the pseudoscience of intelligent design. According to Dembski, the concept can formalize a property that singles out patterns that are both specified and complex, where in Dembski's terminology, a specified pattern is one that admits short descriptions, whereas a complex pattern is one that is unlikely to occur by chance. Proponents of intelligent design use specified complexity as one of their two main arguments, alongside irreducible complexity.
Darwin's Black Box: The Biochemical Challenge to Evolution is a book by Michael J. Behe, a professor of biochemistry at Lehigh University in Pennsylvania and a senior fellow of the Discovery Institute's Center for Science and Culture. In the book Behe presents his notion of irreducible complexity and argues that its presence in many biochemical systems therefore indicates that they must be the result of intelligent design rather than evolutionary processes. In 1993, Behe had written a chapter on blood clotting in Of Pandas and People, presenting essentially the same arguments but without the name "irreducible complexity," which he later presented in very similar terms in a chapter in Darwin's Black Box. Behe later agreed that he had written both and agreed to the similarities when he defended intelligent design at the Kitzmiller v. Dover Area School District trial.
In creationism, a religious view based on a literal reading of the Book of Genesis and other biblical texts, created kinds are purported to be the original forms of life as they were created by God. They are also referred to in creationist literature as kinds, original kinds, Genesis kinds, and baramins.
Cheri Pierson Yecke is an author and retired conservative Republican professor in the United States.
Paul A. Nelson is an American philosopher, noted for his advocacy of the pseudosciences of young earth creationism and intelligent design.
Flock of Dodos: The Evolution-Intelligent Design Circus is a documentary film by American marine biologist and filmmaker Randy Olson. It highlights the debate between proponents of the concept of intelligent design and the scientific evidence and consensus that supports evolution, as well as the potential consequences of science rejection.
Pharyngula, a blog founded and written by PZ Myers, is hosted on ScienceBlogs and on FreeThoughtBlogs (2011–present). In 2006 the science journal Nature listed it as the top-ranked blog written by a scientist based on popularity. The blog addresses a range of topics, including Myers's academic specialty, biology. It has become particularly well known for Myers's writing style and for his criticism of intelligent design and creationism. In 2009, Hemant Mehta ranked Pharyngula the most popular atheist blog, based on subscriber levels and other factors.
Objections to evolution have been raised since evolutionary ideas came to prominence in the 19th century. When Charles Darwin published his 1859 book On the Origin of Species, his theory of evolution initially met opposition from scientists with different theories, but eventually came to receive near-universal acceptance in the scientific community. The observation of evolutionary processes occurring has been uncontroversial among mainstream biologists since the 1940s.
The Discovery Institute has conducted a series of related public relations campaigns which seek to promote intelligent design while attempting to discredit evolutionary biology, which the Institute terms "Darwinism". The Discovery Institute promotes the pseudoscientific intelligent design movement and is represented by Creative Response Concepts, a public relations firm.
This timeline of intelligent design outlines the major events in the development of intelligent design as presented and promoted by the intelligent design movement.
Explore Evolution: The Arguments For and Against Neo-Darwinism is a controversial biology textbook written by a group of intelligent design supporters and published in 2007. Its promoters describe it as aimed at helping educators and students to discuss "the controversial aspects of evolutionary theory that are discussed openly in scientific books and journals but which are not widely reported in textbooks." As one of the Discovery Institute intelligent design campaigns to "teach the controversy" its evident purpose is to provide a "lawsuit-proof" way of attacking evolution and promoting pseudoscientific creationism without being explicit.
The Biologic Institute was a section of the Discovery Institute created to give the organization a facade of conducting biological research with the aim of producing experimental evidence of intelligent design creationism, funded by the Discovery Institute. It claimed offices in Redmond, Washington and laboratories in the Fremont neighborhood of Seattle, Washington. Instead Biologic Institute consisted solely of a rented office space in Redmond which is no longer in use for several years although the web domain is still renewed. The 'research' listed for the group consists mainly of random and often irrelevant works by Intelligent Design supporters going back to their graduate school years. Several are notably articles, books or internally published content from Discovery's 'BioComplexity' journal which is not a legitimate scientific journal.
Expelled: No Intelligence Allowed is a 2008 American documentary-style propaganda film directed by Nathan Frankowski and starring Ben Stein. The film contends that there is a conspiracy in academia to oppress and exclude people who believe in intelligent design. It portrays the scientific theory of evolution as a contributor to communism, fascism, atheism, eugenics, and in particular Nazi atrocities in the Holocaust. Although intelligent design is a pseudoscientific religious idea, the film presents it as science-based, without giving a detailed definition of the concept or attempting to explain it on a scientific level. Other than briefly addressing issues of irreducible complexity, Expelled examines intelligent design purely as a political issue.
Paul Zachary Myers is an American biologist who founded and writes the Pharyngula science blog. He is associate professor of biology at the University of Minnesota Morris (UMM) where he works in the field of developmental biology. He is a critic of intelligent design and the creationist movement and other pseudoscientific concepts.
The crocoduck is a fictitious hybrid animal with the head of a crocodile and the body of a duck proposed in 2007 by young-Earth creationists Ray Comfort and Kirk Cameron to be an animal that should exist, were their misconceptions about the theory of evolution true. The animal became an internet meme used to ridicule common misrepresentations of evolution, namely, that the theory predicts forms intermediate between any two currently living organisms.
