Natural Selection Definition - Investopedia

WebNatural selection is a driving force in evolution and can generate populations that are better adapted to survive and successfully reproduce in their environments. However, natural selection cannot produce the perfect organism. Natural selection can only select on existing variation in the population. It does not create anything from scratch. WebNatural selection acts on populations through a specific trait. Which statement must be true about that trait? answer choices The trait is resistant to mutations. The trait is passed on genetically to the next generation. Most forms of the trait have the same impact on survival. The trait is the same for all organisms.
