The theory of evolution is most accurately described as Group of answer choices A. Nn opinion that some scientists hold about how life originated on Earth. B. An overarching explanation, supported by much evidence, for how populations change over time and new species arise from ancestral species. C. One possible explanation, among several scientific alternatives, about how species have come into existence.

(a) is based on the sequence of fossils in rock layers (b) uses genetics to explain the source of hereditary variation that is essentialto natural selection (c) was first proposed by ancient Greek scholars (d) considers the influence of the geographic distribution of organisms on their evolution (e) is reinforced by homologies that are explained by common descent
With regard to biological evolution, which of the following statements is incorrect? Explain why.A. During its lifetime, an animal evolves to become better adaptedto its environment.B. The process of biological evolution has produced species thatare better adapted to their environments.C. When an animal is better adapted to its environment, the process of natural selection makes it more likely that the animalwill reproduce.
