“Others have deduced that, because of certain similarities between different forms of life, there has been a natural selection of the species or organic evolution from one form to another. . . . To me, such theories are unbelievable. . . . It is incumbent upon each informed and spiritually attuned person to help overcome such foolishness of those who would deny divine creation or think that man simply evolved.” Source: The Power Within Us. (Deseret Book).
Elder Boyd K. Packer:
"The rules and principles [of creation] are in the scriptures. The revelations make it very clear that mankind is the offspring of Heavenly Parents. We have in God our Father and a Heavenly Mother the pattern of our parentage. . . . No lesson is more manifest in nature than that all living things do as the Lord commanded them in the Creation. They reproduce after their own kind. They follow the pattern of their parentage. Everyone knows that. Every four-year-old knows that! A bird will not become an animal nor a fish. A mammal will not beget a reptile. . . . Each is a child of God. He is not a monkey; neither were his ancestors."
