Genetic variation and natural selection drive adaptations in populations to improve survival.
Genetic variability within a population produces traits that can be adaptations favored by natural selection. This variation allows some individuals to adapt to their environment, increasing their chances of survival and reproduction.
Natural selection works by selecting for alleles that confer beneficial traits or behaviors, while selecting against those for deleterious qualities. Individuals with advantageous traits will have a higher likelihood of passing on their genes to the next generation.
Adaptations favored by natural selection contribute to a population's ability to survive changing environmental conditions, highlighting the importance of genetic variation.
