Directional Selection Example In Humans at Justin Dale blog

Directional Selection Example In Humans. A classic example of stabilising selection can be seen in human birth weights. Learn how it occurs in humans and. 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. The environment created a selection pressure which favored giraffes with longer necks who could reach more food in the trees. Learn what directional selection is and how it causes a population to evolve towards one end of a trait spectrum. Learn about directional selection, a form of natural selection that moves the trait mean toward the optimum for the environment. At the same time, there was selection pressure against giraffes with shorter necks. In directional selection, a population’s genetic variance shifts toward a new phenotype when exposed to environmental changes. An example of directional selection is giraffe neck lengths. Directional selection is a form of natural selection that favors extreme traits in response to environmental changes.
