An individual attribute could increase in a population within the following 2 ways:-
(a) Natural selection: if an attribute is useful to a population, it’ll increase naturally.
As an example – inexperienced colorize beetles is favorable because it helps them in camouflage against the predators.
(b) Genetic drift: if a population faces AN accident such majority of its members get killed, the remaining members can pass away their traits to the following generations. This may result in a rise of the attribute within the population.
