In the field of Population Genetics, a population is undergoing Evolution when: A population is said to be at "equilibrium", with regard to its distributions of alleles in the "gene pool". A selective pressure from the environment is no longer acting on a population, allowing for the evolution event to remain stable. O Mating between individuals is completely random, O There is a change in the number of alleles (i.e. allele frequency) present in a population, from one generation to the next.

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.
