Matural selection is based on what?
Change

Natural selection is based on the idea that individuals within a species exhibit variation in their traits, and that some of these variations make them better suited to their environment. Those with advantageous traits are more likely to survive, reproduce, and pass those traits onto the next generation, leading to gradual evolutionary changes over time.

In real-world terms, natural selection can be observed in various scenarios, such as antibiotic resistance in bacteria. When exposed to antibiotics, bacteria with mutations that confer resistance thrive and reproduce, while those without such traits are eliminated, leading to a population that is entirely resistant to the drug over time. This phenomenon illustrates how rapidly the process can occur in response to environmental pressures!
