natural selection acts by differential survival and reproduction
Explanation:
According to the evolutionary theory proposed by Darwin (1859), selection natural can be defined as the evolutionary mechanism of differential survival and reproduction by which individuals adapt and change over time. Natural selection states that individuals better adapted to their environments will have more chances to survive and reproduce, thereby having more chances to pass their genes to the next generation. Natural selection acts on any heritable phenotypic characteristic, while selective pressure is any environmental factor that influences an individual's survival/reproduction.
