Questions and answers about creationism and evolution.

The purpose of the talk.origins newsgroup is to provide a forum for discussion of issues related to biological and physical origins. See the talk.origins Newsgroup Welcome FAQ.

The purpose of the TO Archive is to provide easy access to the many FAQ (frequently asked question) files and essays have been posted to the Usenet newsgroup talk.origins. The Archive exists expressly to provide mainstream scientific responses to the many issues that appear in the talk.origins newsgroup. See the Talk.Origins Archive's Welcome Page and the Talk.Origins Archive's Must-Read FAQs.

Biological evolution is a change in the genetic characteristics of a population over time. That this happens is a fact. Biological evolution also refers to the common descent of living organisms from shared ancestors. The evidence for historical evolution -- genetic, fossil, anatomical, etc. -- is so overwhelming that it is also considered a fact. The theory of evolution describes the mechanisms that cause evolution. So evolution is both a fact and a theory. See the Evolution is a Fact and a Theory FAQ, the Introduction to Evolutionary Biology FAQ and the Five Major Misconceptions about Evolution FAQ: Evolution is Only a theory.

No. Many people of Christian and other faiths accept evolution as the scientific explanation for biodiversity. See the God and Evolution FAQ and the Interpretations of Genesis FAQ.

No. Evolutionary theory is in exactly the same condition as any other valid scientific theory, and many criticisms of it that rely on philosophy are misguided. See the Evolution and Philosophy FAQ.

Due to the rarity of preservation and the likelihood that speciation occurs in small populations during geologically short periods of time, transitions between species are uncommon in the fossil record. Transitions at higher taxonomic levels, however, are abundant. See the Transitional Vertebrate Fossils FAQ, the Fossil Hominids FAQ, 29 Evidences for Macroevolution: Intermediate and Transitional Forms, the Punctuated Equilibria FAQ, and the February 1998 Post of the Month Missing links still missing!?.

Evolution has been observed, both directly and indirectly. It is true. See the Five Major Misconceptions about Evolution FAQ: Evolution Has Never Been Observed and 29 Evidences for Macroevolution.

Speciation has been observed, both in the laboratory and in nature. See the Observed Instances of Speciation FAQ and another FAQ listing some more observed speciation events.

No. In fact, humans (and other animals) have many suboptimal characteristics. See the Evidence for Jury-Rigged Design in Nature FAQ.

Evolution is not simply a result of random chance. It is also a result of non-random selection. See the Evolution and Chance FAQ and the Five Major Misconceptions about Evolution FAQ: Evolution Proceeds by Random Chance.

Evolution does not violate the second law of thermodynamics. Order emerges from disorder all the time. Snowflakes form, trees grow, and embryos develop, etc. See the Second Law of Thermodynamics, Evolution, and Probability FAQs and the Five Major Misconceptions about Evolution FAQ: Evolution Violates the 2nd Law of Thermodynamics.

The Darwin deathbed story is false. And in any case, it is irrelevant. A scientific theory stands or falls according to how well it is supported by the facts, not according to who believes it. See the Lady Hope Story FAQ.

According to numerous, independent dating methods, the earth is known to be approximately 4.5 billion years old. Most young-earth arguments rely on inappropriate extrapolations from a few carefully selected and often erroneous data points. See the Age of the Earth FAQ and the Talk.Origins Archive's Young Earth FAQs.

Radiometric isochron dating techniques reveal whether contamination has occurred, while numerous theoretical calculations, experiments, and astronomical observations support the notion that decay rates are constant. See the Isochron Dating FAQ and the Age of the Earth FAQ.

Barry Setterfield's hypothesis of a decay in the speed of light was based on flawed extrapolations from inaccurate measurements, many of which were taken hundreds of years ago. See the C-Decay FAQ.

No. The Earth's magnetic field is known to have varied in intensity and reversed in polarity numerous times throughout the planet's history. See the Alleged Decay of the Earth's Magnetic Field FAQ.

No. A global flood cannot explain the sorting of fossils observed in the geological record. This was recognized even prior to the proposal of evolutionary theory. See the Problems with a Global Flood FAQ, the April 2002 Post of the Month A Flood Geologist Recants and the Talk.Origins Archive's Flood Geology FAQs.

They have natural explanations: tree-roots that grew into soft, underlying layers of clay, and fossils found in inclined strata. They can also be observed forming in modern environments. See the "Polystrate" Fossils FAQ.

The "man-tracks" of the Paluxy Riverbed in Glen Rose, Texas were not man tracks at all. Some were eroded dinosaur tracks, and others were human carvings. See the The Texas Dinosaur/"Man Track" Controversy FAQ.

The producers of America's 1993 CBS television show, "The Incredible Discovery of Noah's Ark," were hoaxed. Other ark discovery claims have not been substantiated. See the Sun Pictures and the Noah's Ark Hoax FAQ.

And irrelevant. Scientists don't claim that cells came into being through random processes. They are thought to have evolved from more primitive precursors. See the Probability of Abiogenesis FAQs.

The quality of an argument is not determined by the credentials of its author. Even if it was, a number of well-known creationists have questionable credentials. Furthermore, many creationists have engaged in dishonest tactics like quoting out of context or making up references. See the Suspicious Creationist Credentials FAQ, the Talk.Origins Archive's Creationism FAQs, Quotations and Misquotations and Creationist Arguments: Misquotes

No, he simply claimed that certain written legends must have described real events. See the Talk.Origins Archive's Catastrophism FAQs and the Velikovsky FAQ.

"Intelligent design" (ID) advocates often use the very same arguments that the young-earth creationists have used in the past. The Archive does have some FAQs on Behe's "irreducible complexity", Jonathan Wells's "icons of evolution", and Dembski's "specified complexity" (see questions below). Further essays on "intelligent design" can be found on our sister site, TalkDesign [off site], and at TalkReason [off site]. "The Quixotic Message," or "No Free Hunch" [off site] deals with ID claims in a humorous manner.

Behe's "irreducible complexity" considers only an unrealistically simplistic model of evolution. Evolutionary mechanisms that Behe doesn't consider, such as functional change and coevolution, make irreducible complexity not only possible, but expected. See Irreducible Complexity and Michael Behe FAQs and Irreducible Complexity Demystified [off site].

Scientists have been complaining for decades about the poor quality of science instruction in school and about the content of science textbooks. However, Dr. Wells's arguments include many false statements, many misunderstandings of the science involved, and many misunderstandings of the significance of the subjects that he pontificates on. See the Icons of Evolution FAQs and The Talented Mr. Wells [PDF format, off site].

The sophistication of Dembski's arguments is superficial. One of the most thorough examinations of Dembski's ideas is available on the Archive. See: Not a Free Lunch But a Box of Chocolates, A Presentation Without Arguments [off site], Mr. Dembski's Compass [off site] and The AntiEvolutionists: William A. Dembski [off site].

That is not even remotely true. See: The Imminent Demise of Evolution: The Longest Running Falsehood in Creationism [off site], Project Steve: Humorous Testing of the Scientific Attitudes Toward "Intelligent Design," and Amicus Curiae Brief of 72 Nobel Laureates

Kent Hovind's $250,000 challenge is a propaganda ploy and nothing more, rather like the "doctorate" Hovind claims from Patriot University. See: Kent Hovind FAQs: Examining "Dr. Dino."

Yes, we do. We keep a copy of the "International Flat Earth Society" flyer here to document that real people in modern times do assert that the earth is flat, not because we think the earth is flat See: Documenting the Existence of "The International Flat Earth Society."

You might start with the talk.origins FAQs. If, however, you want a thorough understanding of evolution, a library would be a more appropriate place to look. The following FAQs provide some good references: the Creation/Evolution Reading List, the Introduction to Evolutionary Biology FAQ, the "What is Evolution?" FAQ, and the Talk.Origins Archive's Evolution FAQs.

We encourage readers not to take our word on the issues, but rather to look at the primary literature and evaluate the evidence. While materials on the Archive have not necessarily been subjected to formal peer-review, many have been subjected to several cycles of commentary in the newsgroup prior to being added to the Archive. Most of our materials provide links and/or bibliographic references to enable the reader to evaluate the evidence for themselves. While anyone can decide to ignore our materials, the Archive has been recognized as a valuable online resource by many well-known groups, magazines, and individuals. Further, a number of college courses have chosen to use materials from the Archive in their coursework. See: Awards, Honors, and Favorable Notices for The Talk.Origins Archive.
