Answer:
The most appropriate answer would be "Desirable traits can be selected for and bred in offspring".
Charles Darwin gave the theory of evolution and explained the process of natural selection.
Natural selection is a gradual process by which nature favors the survival of organisms present with particular traits.
By natural selection, organisms with those particular or desirable traits tend to reproduce and survive more.
These desirable traits are passed onto the offspring and gradually spread throughout the population.
