Question

difference between natural selection and mutation theory

Answer 1

Natural selection is a macroscopic tendency for genes, or particular combinations of genes, that survive to persist in the future. A.k.a. only the survivors continue to exist.

OR

Mutation is an off-chance that a gene that is passed on to offspring will be altered prior to getting passed on. A.k.a. A genetic typo might change a particular gene so it behaves in a new way (or it might not have any noticeable effect at all).
