In the early nineteenth century, the French scientist Georges Cuvier provided conclusive evidence of the extinction of species on Earth. Although Cuvier correctly asserted that a series of catastrophes led to these extinctions, he could not provide a testable explanation of the source of the new animals and plants that appeared after the extinction of older forms. How would you argue that modern evolutionary theory provides an explanation for the proliferation of new forms of life after mass extinctions?

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.
