talk.origins (often capitalised to Talk.Origins or abbreviated as t.o.) is a moderated Usenet discussion forum concerning the origins of life, and evolution. It remains a major venue for debate in the creation-evolution controversy, and its official purpose is to draw such debates out of the science newsgroups, such as sci.bio.evolution and sci.bio.paleontology.
The first post to talk.origins was a starter post by Mark Horton, dated 5 September 1986.
The group was originally created as the unmoderated newsgroup net.origins as a 'dumping ground' for all the various flame threads 'polluting' other newsgroups, then renamed to talk.origins as part of the Great Renaming. Subsequently, after discussion on the newsgroup, the group was voted to be moderated in 1997 by the normal USENET RFD/CFV process, in which only spam and excessive crossposting are censored. The moderator for the newsgroup is David Iain Greig (and technically Jim Lippard as alternate/backup).
The group is characterized by a long list of in-crowd jokes like the fictitious University of Ediacara, the equally fictitious Evil Atheist Conspiracy which allegedly hides all the evidence supporting Creationism, a monthly election of the Chez Watt-award for "statements that make you go 'say what', or some such.",pun cascades, a strong predisposition to quoting Monty Python and a habit of calling penguins "the best birds".
Apart from the humor, the group includes rebuttals to creationist claims. There is an expectation that any claim is to be backed up by actual evidence, preferably in the form of a peer-reviewed publication in a reputable journal. The group as a whole votes for a PoTM-award (Post of The Month), which makes it into the annals of TalkOrigins Archive.
