1• During reproduction, copying of DNA takes
place, which is not 100 % accurate, thereby causing variations.
2• If these variations are favourable they help the individuals to survive and pass these variations to their progeny.
3• Depending upon the nature of variations, different individuals have different advantages, which promotes their survival like bacteria which can withstand heat will survive better in heat wave.
