WebHowever, the misuse or overuse of these antibiotics, natural resistance that existed even before the antibiotics were discovered, genetic variations in bacteria, natural selection, … WebNatural selection - this helps to survive and breed also to help them to pass their genetics (DNA) to the next generation. Examples like frogs of light and darker skin colour. But this doesn't mean the allele for the light skinned frog is gone completely and instead became recessive. Evolution can take place because natural selection has occurred.
