Final answer:
Natural selection, or adaptation, is the process that leads to individuals with traits better suited to their environment. This allows them to have an advantage over others in surviving and reproducing.
Step-by-step explanation:
Natural selection is the process that results in individuals with traits that are better suited to their environment. This process, also known as adaptation, allows certain individuals to have an advantage over others in surviving and reproducing. For example, if the selective pressure is a predator, individuals who are best able to avoid being eaten will survive and reproduce at a higher rate. As a result, over time, individuals with favorable genetic traits become more prevalent in the population.
