It is the process by which individuals with certain advantageous traits are more likely to survive and reproduce, passing on their genes to the next generation. Over time, natural selection can lead to the accumulation of adaptations that enhance an organism’s ability to survive and reproduce in its specific environment.

Importance of Genetic Variation

Genetic variation is essential for the survival and evolution of species. It provides the raw material upon which natural selection acts, allowing populations to adapt to changing environments and increasing their chances of survival.

Greater genetic variation within a population increases the probability that some individuals will possess traits that make them better suited to survive and reproduce in a changing environment. This variation serves as a hedge against environmental uncertainty and provides the population with the flexibility needed to adapt to new challenges.
