Space prevents detailing the challenges to evolving life from simple to complex. In brief, evolutionists propose two mechanisms to move evolution upward: natural selection and genetic mutations. Natural selection enables an organism to adapt to its environment, but it never creates any new genetic information. Genetic mutations do a fine job of deleting, duplicating, or damaging existing genetic information, but they, likewise, never create any new genetic information. In other words, these proposed mechanisms can account for variation within an organism kind (think variation in the dog kind), but they cannot create new kinds (like a green haired dog or moving a dog to a horse).
