What is diversifying natural selection

Find two consecutive natural number the sum of whose reciprocal is 11/30.Directional selection is one of three widely studied types of natural selection, in addition to stabilizing selection and disruptive.Diversifying or disruptive selection increases genetic variance when natural selection selects for two or more extreme phenotypes that each have specific advantages.In diversifying or disruptive selection, average or intermediate phenotypes are often less fit than either extreme phenotype and are unlikely to feature prominently in a population.The others are directional selection (which decreases the genetic variation), diversifying or disruptive selection (which shifts genetic variation to adjust to environmental changes), sexual selection (which.Directional selection, stabilizing selection and disruptive selection are three types of natural selection.

Diversifying selection, much like directional selection, drives the population towards the extremes of the trait.In three to five sentences, explain how the fossil record provides evidence for the idea of natural selection.Natural selection is the process through which populations of living organisms adapt and change.While some traits are discrete and have specific variations (think eye color), other traits are continuous, and exists as a wide range of nearly infinite values (think height).if a discrete trait goes through a directional selection, only one.Darwin's grand idea of evolution by natural selection is relatively simple but often misunderstood.The disruptive selection will cause organsisms with intermediate traits to reproduce less, and will allow those organisms with extreme traits to reproduce more.

This causes the alleles for the extreme traits to increase in frequency.What is diversifying natural selection.They are also examples of adaptive evolution.This happens when a population encounters 2 (or more) separate environments in different areas of the region it occupies.
