<h3>What is evolution?</h3>
Evolution is the shift in a biological population's heritable traits over successive generations. These traits are the result of genes that are expressed during reproduction and transferred from parent to offspring. Mutation, genetic recombination, and other causes of genetic diversity frequently result in different traits existing within a population. When these variations are subjected to evolutionary processes like natural selection (which includes sexual selection) and genetic drift, specific traits within a population start to become more or less prevalent. This is when evolution happens.

Like mentioned in the question this is basically any kind of mechanism that prevents fertilization from occurring.
