The largest church within Mormonism, The Church of Jesus Christ of Latter-day Saints (LDS Church), takes no official position on whether or not biological evolution has occurred, or on the validity of the modern evolutionary synthesis as a scientific theory. In the 20th century, the LDS Church published doctrinal statements on the origin of man and creation. In addition, individual leaders of the LDS Church have expressed a variety of opinions on evolution, many of which have affected the beliefs and perceptions of Latter-day Saints.
The LDS Church has stated that it "has no official position on evolution, and each member is entitled to his or her own personal views on the subject".
Some general authorities and lay members of the LDS Church have considered evolution to be at variance with scriptural teaching. Apostles Joseph Fielding Smith and Bruce R. McConkie were among the most well known advocates of this position. Other church authorities and members have seen much of value in evolutionary theory, even if they have not endorsed every aspect of it. Examples of this approach include B. H. Roberts, James E. Talmage, John A. Widtsoe, Henry B. Eyring, and Gordon B. Hinckley.
While maintaining its "no position" stance, the LDS Church has produced a number of official publications that have included discussion and unofficial statements from these various church leaders on evolution and the "origin of man." These statements generally adopt the position, as a church-approved encyclopedia entry states, "[t]he scriptures tell why man was created, but they do not tell how, though the Lord has promised that he will tell that when he comes again."
The first official statement on the issue of evolution was in 1909, which marked the centennial of Charles Darwin's birth and the 50th anniversary of his On the Origin of Species. In that year, the First Presidency, led by Joseph F. Smith as church president, issued a statement declaring that the church, "basing its belief on divine revelation, ancient and modern, proclaims man to be the direct and lineal offspring of Deity." This teaching regarding the origin of man differs from traditional Christianity's doctrine of creation, referred to by some as "creationism", which consists of belief in a fiat creation. In addition, the statement declares human evolution as one of the "theories of men", but falls short of explicitly declaring it untrue or evil. It states:
