Question

Mutations are important for evolution because they _____

Answer 1

Mutations are important for evolution because they are the ultimate source of all genetic variation

Step-by-step explanation:

Evolution is the change of genetics in populations over time while Mutation is a change in DNA within a single cell of a single individual. Mutation is necessary and mandatory and considered as the first step of evolution because it creates a new DNA sequence for a particular gene and creating a new allele. The majority of mutations happen in somatic cells and cannot be passed on to descendants.

Answer 2

C. They are source of new genetic variation

Explanation

Mutation result in genetic changes allowing species to develop new traits because the DNA changes thus affecting how the living organism will behave, look and adjust to physiology processes. Through mutation, evolution has been achieved because living things can survive as they fit into new environment with new traits acquired through mutation.
