There are several religious organizations that have issued statements advocating the teaching of evolution in public schools. In addition, the Archbishop of Canterbury, Dr. Rowan Williams, issued statements in support of evolution in 2006. The Clergy Letter Project is a signed statement by 12,808 (as of 28 May 2012) American Christian clergy of different denominations rejecting creationism organized in 2004. Molleen Matsumura of the National Center for Science Education found, of Americans in the twelve largest Christian denominations, at least 77% belong to churches that support evolution education (and that at one point, this figure was as high as 89.6%).

It does not occur itself, according to the Ahmadiyya Muslim Community. The Ahmadis do not believe Adam was the first human on earth, but merely the first prophet to receive a revelation of God. Baha'i Faith A fundamental part of `Abdul-Bahá's teachings on evolution is the belief that all life came from the same origin: "the origin of all material life is one..." He states that from this sole origin, the complete diversity of life was generated: "Consider the world of created beings, how varied and diverse they are in species, yet with one sole origin" He explains that a slow, gradual process led to the development of complex entities: Catholic Church The 1950 encyclical Humani generis advocated scepticism towards evolution without explicitly rejecting it; this was substantially amended by Pope John-Paul II in 1996 in an
