natural selection

listen to the pronunciation of natural selection
English - Turkish
doğal ayıklanma
(Biyoloji) Doğal seçme, (doğal seçilim veya Doğal Ayıklama ya da Doğal Seleksiyon) dış çevreye uyum konusunda daha elverişli özelliklere sahip birey organizmaların, bu elverişli özelliklere sahip olmayan diğer bireylere göre yaşama ve üreme şanslarının daha yüksek olması ve bunun sonucu olarak genlerini yeni kuşaklara aktarma yönünden daha avantajlı olmalarıyla işleyen mekanizmadır. Böylece dış ortama uyum sağlamakta sorunlar yaşayan bireyler ve genler organizma popülasyonundan tasfiye edilmiş olmaktadır

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
process in which species that are best adapted to their environments will survive
Natural selection is a process by which species of animals and plants that are best adapted to their environment survive and reproduce, while those that are less well adapted die out. Natural selection ensures only the fittest survive to pass their genes on to the next generation. The process in nature by which, according to Darwin's theory of evolution, only the organisms best adapted to their environment tend to survive and transmit their genetic characteristics in increasing numbers to succeeding generations while those less adapted tend to be eliminated. the process by which only plants and animals that are naturally suitable for life in their environment will continue to live and breed, while all others will die out evolution survival of the fittest survival. Process that results in adaptation of an organism to its environment by means of selectively reproducing changes in its genotype. Variations that increase an organism's chances of survival and procreation are preserved and multiplied from generation to generation at the expense of less advantageous variations. As proposed by Charles Darwin, natural selection is the mechanism by which evolution occurs. It may arise from differences in survival, fertility, rate of development, mating success, or any other aspect of the life cycle. Mutation, gene flow, and genetic drift, all of which are random processes, also alter gene abundance. Natural selection moderates the effects of these processes because it multiplies the incidence of beneficial mutations over generations and eliminates harmful ones, since the organisms that carry them leave few or no descendants.
