Is Evolution Directional. While some traits are discrete and have specific. In the longer term, evolution produces new species through splitting ancestral populations of organisms into new groups that cannot or will not interbreed. A directional selection is a force in nature that causes a population to evolve towards one end of a trait spectrum. When the environment changes, populations will often undergo directional selection, which selects for phenotypes at one end of the spectrum of existing. Directional selection is a type of natural selection in which the phenotype (the observable characteristics) of the species tends toward one extreme rather the mean phenotype or the opposite extreme phenotype. Directional selection does the “heavy lifting” of evolution by tending to move the trait mean toward the optimum for the. The directional selection theory says that an extreme phenotype (characteristics or traits) is favored over other phenotypes and this causes the allele frequency (how often the variant of a gene shows up in a population) to shift over time in favor of the extreme phenotype.
