What is a reason that speciation can occur?         Organisms within a species are brought into closer proximity by a physical barrier.         Organisms within an ecosystem make adaptions that involve different breeding times or interactions.          Organisms develop traits that are not beneficial to their survival, and these traits are passed from generation to generation.         Organisms develop traits that are beneficial and pass on the same traits to all future generations within the same species.

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.
