Web1044. Natural selection is a mechanism of evolution. Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success. This process causes species to change and diverge over time. Natural selection is one of the ways to account for the millions of species that have lived on Earth.

WebResumen. La selección natural produce microevolución, un cambio en las frecuencias de los alelos a lo largo del tiempo, en la que los alelos que aumentan la adecuación de los organismos se vuelven más comunes en la población a lo largo de varias generaciones.

WebIn On the Origin of Species by Natural Selection (1859), Charles Darwin described four requirements for evolution by natural selection: the trait under selection must be variable in the population, so that the encoding gene has more than one variant, or allele. the trait under selection must be heritable, encoded by a gene or genes WebNatural selection without the asteroid (i.e. genetic drift) would have produced significantly less alteration in the gene pool, (and subsequently allele frequency), at least for the same time ...
