Natural Selection
Natural selection is the gradual, non-random process by which biological traits become either more or less common in a population as a function of differential reproduction of their bearers. It is a key mechanism of evolution. The term "natural selection" was popularized by Charles Darwin who intended it to be compared with artificial selection, what we now call selective breeding.

Famous quotes containing the words natural and/or selection:
“A person who can’t pay gets another person who can’t pay to guarantee that he can pay. Like a person with two wooden legs getting another person with two wooden legs to guarantee that he has got two natural legs. It don’t make either of them able to do a walking-match.”
—Charles Dickens (1812–1870)
“Every writer is necessarily a critic—that is, each sentence is a skeleton accompanied by enormous activity of rejection; and each selection is governed by general principles concerning truth, force, beauty, and so on.... The critic that is in every fabulist is like the iceberg—nine-tenths of him is under water.”
—Thornton Wilder (1897–1975)
