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.
