what is natural selection and it's types
Answers
Answer:
Natural selection thus selects for very different looking animals to fill the different niches of the ecosystem.
Type 1: Stabilizing Selection
Most traits in the animal kingdom can be described by a bell curve, in terms of their distribution. Most animals of a certain species tend to show the same trait or feature, of relatively the same size. There are always some exceptions of larger or smaller traits in certain individuals, but generally, most individuals sit somewhere in the middle.
Type 2: Directional Selection
Directional selection is a type of natural selection that occurs when one side of the spectrum of a certain trait is favored over the other
Type 3: Diversifying Selection
Much like directional selection, diversifying selection pushes the population towards the extremes of the trait. This type of selection is also called disruptive selection. Diversifying selection, in contrast to directional selection, pushes the trait both ways.
Type 4: Sexual Selection
While you can classify natural selection in terms of the effects it has on the population, you can also view it as the interaction between organisms with different relationships. Sexual selection is a kind of natural selection in which the different genders in a species exert forces on each other that changes their appearance or traits
