Explanation:
Natural selection is a theory that states organisms adapts to its environment due to differences in their phenotypes. So, <u>individuals with favorable traits are more likely to survive and reproduce</u>. It is a key mechanism of evolution, which is the change in traits of a population over generations.
<u>Populations respond to natural selection if they contain heritable variation </u>among them, wich means that individuals differ in the traits they transmit to their offspring.
Because of the environmental selection pressures, individuals produce more offspring than their environment can support. <u>The pressure determines which individuals will survive and reproduce</u>, while others will die because of predation or diseases. So, natural selection is based on the observations of adapted individuals.
