Catholic Church and evolution
Since the publication of Charles Darwin's On the Origin of Species in 1859, the attitude of the Catholic Church on the theory of evolution has slowly been refined. Early contributions to the development of evolutionary theory were made by Catholic scientists such as Jean-Baptiste Lamarck and the Augustinian monk Gregor Mendel. For nearly a century, the papacy offered no authoritative pronouncement on Darwin's theories. In the 1950 encyclical Humani generis, Pope Pius XII confirmed that there is no intrinsic conflict between Christianity and the theory of evolution, provided that Christians believe that the individual soul is a direct creation by God and not the product of purely material forces. Today, the Church supports theistic evolution(ism), also known as evolutionary creation, although Catholics are free not to believe in any part of evolutionary theory.The Catholic Church holds no official position on the theory of creation or evolution, leaving the specifics of either theistic evolution or literal creationism to the individual within certain parameters established by the Church. According to the Catechism of the Catholic Church, any believer may accept either literal or special creation within the period of an actual six day, twenty-four hour period, or they may accept the belief that the earth evolved over time under the guidance of God. Catholicism holds that God initiated and continued the process of his evolutionary creation, that Adam and Eve were real people (the Church rejects polygenism) and affirms that all humans, whether specially created or evolved, have and have always had specially created souls for each individual.Catholic schools in the United States and other countries teach evolution as part of their science curriculum. They teach the fact that evolution occurs and the modern evolutionary synthesis, which is the scientific theory that explains how evolution proceeds. This is the same evolution curriculum that secular schools teach. Bishop Francis X. DiLorenzo of Richmond, chair of the Committee on Science and Human Values, wrote in a letter sent to all U.S. bishops in December 2004: ""... Catholic schools should continue teaching evolution as a scientific theory backed by convincing evidence. At the same time, Catholic parents whose children are in public schools should ensure that their children are also receiving appropriate catechesis at home and in the parish on God as Creator. Students should be able to leave their biology classes, and their courses in religious instruction, with an integrated understanding of the means God chose to make us who we are.""
