"Evolution is a law (with several components) that is as well substantiated as any other natural law, whether the law of gravity, the laws of motion or Avogadro's law. Evolution is a fact, disputed only by those who choose to ignore the evidence, put their common sense on hold and believe instead that unchanging knowledge and wisdom can be reached only by revelation." -- Nobel laureate James D. Watson, co-discoverer of the molecular structure of DNA
