(a) is based on the sequence of fossils in rock layers (b) uses genetics to explain the source of hereditary variation that is essential to 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 descentarrow_forwardTest Your Understanding Evaluate and Synthesize 17. EVOLUTION LINK Scientists have proposed various initiatives to detect water vapor, as well as oxygen and carbondioxide, in the atmospheres of distant planets.
