Why is genetic variation important to the process of evolution? (Choose all that apply) If all of the individuals in a population were the same the entire population would be vulnerable to extinction rather than evolut Evolutionary adaptations are the result of a gradual build up of genetic differences over long periods of time Evolution at the population level refers to changes in the gene frequencies in the population over time Individuals must be able to mutate genes in order to adapt to the current situation in their environments

Genetic Evolution

Sexual reproduction produces distinct population variations. Heredity determines the traits and qualities to be passed down to the progeny. Over time, this variation within-species is also affected by the process of human evolution. The study of how genetic variation leads to evolutionary changes is known as genetic evolution. If a trait helps an organism to survive and reproduce, it is more likely to be passed down the generations. It is rare that such traits result in a completely distinct set of traits in descendants than the ancestral population; this can result in the emergence of a new species.
