Outcomes Explain the term natural selection and use examples

Natural Selection Natural selection- evolution of species due to beneficial alleles passing to future generations Genetic variation describes the differences in alleles of a gene within a population

Natural Selection Genetic variations in a species allows natural selection to occur.

Natural Selection Ancestors of the anteater who had slightly longer tongues could get more food and thus have more chance at reproducing. After hundred of thousands of years, the longest tongued individuals keep passing on their genes to produce the modern day anteater.
