Imagine a scenario where you are male and have a triangular head. For some reason, females in your area find triangular heads very attractive, so guys with triangular heads mate and reproduce more than other men. Eventually, all the non-triangular-headed people die out and the whole population of people in your area has triangular heads. This is an example of what?

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.
