Creation Research Society

The Creation Research Society (CRS) is a Christian fundamentalist group that requires of its members belief that the Bible is historically and scientifically true in the original autographs, belief that "original created kinds" of all living things were created during the Creation week described in Genesis, and belief in flood geology.

The organization has produced various publications describing what it calls creation science, including a journal and a creation-based biology textbook; use of the textbook in public schools was ruled unconstitutional in Hendren v. Campbell.

During the first few years of its existence, different beliefs about Creationism and disagreement over its statement of beliefs resulted in various members of the CRS board and voting members being forced out of the organization.
