means The process by which organisms with traits better suited to their environment tend to survive and reproduce more successfully, passing those traits on to future generations.

from Coined by Charles Darwin in his 1859 'On the Origin of Species,' deliberately echoing the language of animal breeders who practiced 'artificial selection' — picking which cows or pigeons bred based on desired traits. Darwin's insight was that nature does the same selecting, but without a breeder's hand: environment and survival do the choosing. He borrowed a human farming term and handed it to the whole of life, which is partly why the phrase still gets misread as implying intention or a selector, when it really describes an outcome — survival and reproduction sorting traits over time, no chooser required.
