adaptive evolution

$[$Choose $]$evolution on a small scale, is defined as a change in the frequency of gene variants, alleles$$differences$,$among individuals in a population$$two species evolve in diverse directions from a common point$$process by which organisms that are better adapted to their environment survive and pass those adaptations onto their offspring$$A heritable trait that helps the survival and reproduction of an organism in its present environment$$similar traits evolve independently in species that do not share a recent common ancestry$$evolution that involves large changes, such as formation of new groups or species$$selecting for beneficial alleles and thus increasing their frequency in the population, while selecting against deleterious alleles and thereby decreasing their frequency$$group of organisms of the same species that are found in the same area and can interbreed
