Darwin's theory consists of 2 parts
Darwin's law of evolution by natural selection <-- law
Darwin's theory of evolution by adaptation <-- theory
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 five 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.
With all this agreement on Darwin's four key tenets, why is there so much fuss about evolution? Ah, but for one small, annoying small point. Modern scientists, following Darwin's last great insight, have proven an accumulation of small changes can lead to an entirely new species, given sufficient time. Creationists deny there is either enough time (i.e. the Earth is only a few thousand years old according to one biblical interpretation), or small changes can never accumulate into a species sized change. Thus, the argument is not over the Evolution of a species by Natural Selection, but the Transmutation between species under any circumstances, including Natural Selection.
So to make it easier for you to understand:
The four parts that are proven are called "Darwin's law of evolution by natural selection" and the fifth part that's still subject to discussion is Darwin's theory of evolution by adaptation
