what is natural selection? click to add text

Explanation:

Natural selection is a key mechanism of evolution. It is the process by which organisms with favorable traits (adaptations) that enhance their survival and reproduction in a particular environment are more likely to pass on those traits to the next generation. Over time, this leads to the gradual change of populations as advantageous traits become more common and less advantageous traits may decrease or disappear. For example, in a population of moths, if there is industrial pollution that darkens tree trunks, moths with darker coloration (a favorable trait in this changed environment) are less likely to be preyed upon by birds, so they survive and reproduce more, leading to an increase in the frequency of the dark - colored trait in the moth population.

Answer:

Natural selection is the process where organisms with heritable traits that increase their survival and reproductive success in a given environment are more likely to pass those traits to offspring, driving evolutionary change.
