Types of Natural Selection. Natural selection can take many forms. To make talking about this easier, we will consider the distribution of traits across a population in graphical form.

Natural selection is one of the mechanisms that drives evolution. To be an active characteristic or trait causing natural selection to take place, the trait has to have the following features: Heritability. A trait can only influence evolution through natural selection if it is passed on from parents to descendants.
