Talk.origins is a Usenet newsgroup devoted to the discussion and debate of biological and physical origins. Most discussions in the newsgroup center on the creation/evolution controversy, but other topics of discussion include the origin of life, geology, biology, catastrophism, cosmology and theology.
The TalkOrigins Archive is a collection of articles and essays, most of which have appeared in talk.origins at one time or another. The primary reason for this archive's existence is to provide mainstream scientific responses to the many frequently asked questions (FAQs) that appear in the talk.origins newsgroup and the frequently rebutted assertions of those advocating intelligent design or other creationist pseudosciences.
Practically anything you could need to defend evolution and rebut relevant ID and creationist claims can be found here. I usually just click on Search the Archive to search for whatever specific material I need. Lots of quality resources there including detailed descriptions of all the different lines of evidence that support evolution, lists of documented speciation events, lists of responses to specific ID and creationst claims, and more.
Many articles relevant to the the creation/ evolution debate and ID which are helpful for defending evolution and pointing out flaws in creation and ID reasoning. Also has a list of relevant books, and links to other relevant sites.
The Committee for Skeptical Inquiry encourages the critical investigation of paranormal and fringe-science claims from a responsible, scientific point of view and disseminates factual information about the results of such inquiries to the scientific community and the public. It also promotes science and scientific inquiry, critical thinking, science education, and the use of reason in examining important issues. To carry out these objectives the Committee:
Maintains a network of people interested in critically examining paranormal, fringe science, and other claims, and in contributing to consumer education
Prepares bibliographies of published materials that carefully examine such claims
Encourages research by objective and impartial inquiry in areas where it is needed
Convenes conferences and meetings
Publishes articles that examine claims of the paranormal
Does not reject claims on a priori grounds, antecedent to inquiry, but examines them objectively and carefully
The Committee is a nonprofit scientific and educational organization, started in 1976. The Skeptical Inquirer is its official journal.
Some of the founding members of CSI include scientists, academics, and science writers such as Carl Sagan, Isaac Asimov, Philip Klass, Paul Kurtz, Ray Hyman, James Randi, Martin Gardner, Sidney Hook, and others. A list of CSI fellows is published in every issue of Skeptical Inquirer magazine.
