Variation is a factor that enables organisms to adapt to the environment. Variation refers to the differences that exist between individuals of the same species, such as differences in physical characteristics, behavior, or genetics. These differences can provide certain individuals with advantages in their environment, allowing them to survive and reproduce more effectively. Over time, these advantageous traits can become more prevalent in a population, leading to adaptation to the environment. Therefore, variation is an important factor that contributes to the survival and evolution of a species.
