Zoology - Evolution Question with Solution | TestHub

Charles Darwin gave the theory of evolution, stating that "all species of organisms arise and develop through the natural selection of small, inherited variations that increase the individual's ability to compete, survive, and reproduce." Also called as Darwinian theory, explained the development of new species where an organisms gathered better suited variations to survive the ever changing environment through the process of over production, competition in resources and natural selection. Although, it could not provide any satisfactory explanation for the source of new variation or adaptations from which natural selection could select. So, Darwin theory fails to explain origin and transmission of variations.
