Definitions for natural selection
Random House Webster's College Dictionary
the process in nature by which forms of life having traits that better enable them to adapt to specific environmental pressures, as changes in climate or competition for food or mates, will tend to survive and reproduce in greater numbers than others of their kind, thus perpetuating those traits in succeeding generations.
Origin of natural selection:
survival, survival of the fittest, natural selection, selection(noun)
a natural process resulting in the evolution of organisms best adapted to the environment
A process by which heritable traits conferring survival and reproductive advantage to individuals, or related individuals, tend to be passed on to succeeding generations and become more frequent in a population, whereas other less favourable traits tend to become eliminated.
A process in which individual organisms or phenotypes that possess favourable traits are more likely to survive and reproduce: the differential survival and reproduction of phenotypes.
The Nuttall Encyclopedia
