Answer 2

Darwin's Law of Evolution by Natural Selection (traditionally referred to as a "theory" to honor Darwin's original treatise, but now confirmed through observation and experiment) consists of four main tenets. First, he describes how species can change in shape and character through selective breeding. No reasonable person, whether creationist or scientist, doubts selective breeding can morph a wolf into a pony-sized mastiff. Or evolve the same wild animal into a comically shrunk, rat-sized Chihuahua. Second, he describes how species are neither completely uniform nor immutable, and how these natural variations are the grist upon which human selective breeding grinds. Once a new characteristic is established, these variations persist from generation to generation, and are systematically and predictably passed from parent to child. Again, all but the most radical creationists accepts these facts, widely employed since the birth of animal husbandry and agriculture. Third, he recognized that Nature, through selective pressures like environmental shifts or changes in predation, can play the role of humans in selective breeding. Whether man selects a long-haired dog for its appearance, or colder winters favor the survival of thick furred over short-haired canines, the result is identical. Again, the power of evolution by Natural Selection is confirmed though field work (such as Darwin's finches), genetic mapping, and the experience of anyone who chooses to listen openly to nature.

Fourth, everyone agrees that, while changes within a species are indisputable and can be observed within a lifetime, no one has ever seen (nor is there a recorded observation after 5000 years of written history) one species transmuting to another. Fish never become fowl, insects never become birds, and monkeys certainly never become humans.
