Darwin's book Origin of Species, published in 1859, proposed the concept of evolution by purely naturalistic causes, especially natural selection. His idea was that the small variations observed within a population of plants or animals would lead to large changes, given a fortuitous environmental change which favored the variant's opportunity for survival and reproduction.

Most arguments against the possibility of mutation as a mechanism for evolution revolve around two premises: that mutations are almost always harmful, and that the idea of their improving rather than harming organisms is contrary to the Second Law of Thermodynamics, which tells us that matter and energy naturally tend toward greater randomness rather than greater order and complexity.

Horses only 15 inches high, 141 tree species in a single acre of tropical rain forest—what spectacular variety we see among living things, both variation within kind and the stupendous number of different kinds.

As more and more scientists adopt the creation model, there ought to be an increasing emphasis on examining data from a creationist viewpoint and a decreasing emphasis on searching out failures of the evolution model to make true or testable predictions.
