How does genetic variation contribute to a species' ability to survive and adapt to changing environments?

Genetic variation allows a species to have different traits and characteristics within its population. This diversity increases the chances that some individuals will have traits that are better suited to survive and thrive in changing environments. As the environment changes, individuals with advantageous traits are more likely to survive and reproduce, passing on their genes to future generations. This process, known as natural selection, helps a species adapt and evolve over time.
