For example, Charles Darwin's theory of evolution by natural selection revolutionized the natural sciences because it replaced the assumption of divine creation with a rational, progressive, and seemingly objective view of extinction and the rise of totally new species of animals. Darwinian theory, because it had great explanatory power, rose from the status of theory to a core assumption or paradigm. Today, if a field biologist writes a paper on the star-nosed mole, he or she need not begin with a complete explanation of natural selection. Evolution by natural selection is assumed, and any theoretical construct to explain the star-nosed mole's existence in a particular environment is rooted in this supposiA tion. Significantly, the social and behavioral sciences have embraced the Darwinian paradigm and developed theories that underpin the notion that humans have "naturally" progressed through time. It is as? 7 sumed that economies, governments, cultures, philosophies, technologies, and social relationships have evolved from the simple to the complex in reaction to various stimuli or as a result of man's innate curiosity.
