Difference Between Natural Selection And Sexual Selection
Option 5
Describe the difference between Darwin’s theories of (a) natural selection and (b) sexual selection.
- Natural Selection
The theory that members of a species each have slight variations from each other, and that these variations have the ability to enable some members of a species a survival advantage in certain environments. As a result of having a variation that increases their likelihood to survive, they are allowed to propagate, and their offspring have an increased likelihood of survival with the passage of the variation. Other members of the species who lack the variation die, and over time the only surviving members of the species are the ones who possessed the variation that gave them the survival advantage.
