Mechanism that drives evolution

WebThere are two main parts to evolution: random mutation, and non random natural selection. Mutations can come from various different mechanisms. Mutations can either be harmful or beneficial. Nearly all mutations are harmful, but a small number are beneficial, and it is these beneficial changes that are at the core of evolution.
