Identify natural selection as a mechanism for the evolution of a population

In natural selection, a species is changed due to a random mutation in offspring that means the offspring is better adapted to survival in that specific environment. As this offspring grows, it out competes it's rivals and they die off leaving it to survive and reproduce passing it's beneficial allele to its own offspring. This chain of passing on the beneficial allele continues until the majority has the beneficial allele meaning the species has evolved.

Yes yes yes very good
