Question

question: why is variation important for natural selection?

Explanation:

Variation is crucial for natural selection as it provides the raw material. Different traits within a population mean some individuals may be better adapted to their environment. These better - adapted individuals are more likely to survive, reproduce, and pass on their genes. Over time, this leads to the evolution of the population. For example, in a population of beetles, if some have a color that better camouflages them from predators (a variation), those beetles are more likely to survive and reproduce, increasing the frequency of the camouflage - related genes in the population.

Answer:

Variation is important for natural selection because it provides the necessary differences among individuals in a population. These differences (traits) can lead to some individuals being more "fit" (better able to survive and reproduce) in a given environment. Through natural selection, the genes of the fitter individuals are more likely to be passed on to the next generation, driving the evolution of the population.
