Natural Selection Definition

noun
In evolution, the process by which certain individuals of a species, having characters that help them adapt to their specific environment, tend to leave more progeny and transmit their characters, while other individuals of the same species, less able to adapt, tend to leave fewer progeny or to die out: over the course of generations, the gene pool of the species comes to reflect this adaptation.
