Which of the following statements is correct? A. Fossils form only from the hard parts of extinct organisms.B. Fossils form in sedimentary rocks.C. Fossils from rocks under other rocks are younger than the fossils found above them.D. Most fossils formed during a few catastrophic events.
The fossil record resembles the living species in the same geographic area. How does this pattern support the theory of evolution by natural selection?A. It is evidence that species can change over time.B. It is evidence of Aristotle"s great chain of being.C. It is evidence of the law of succession.D. It is evidence that Lamarck was right: species become more complex over time.
What trait does not randomly arise but evolves from a once-functional trait when the trait is no longer adaptive?
Why do related species share homologous traits? See Section 22.2 (Page 438) .View Available Hint(s)Why do related species share homologous traits? See Section 22.2 (Page 438) .Related species have adapted to similar environments.Related species have independently evolved homologous traits.Related species inherited homologous traits from a common ancestor.Related species share homologous traits because they are found in the same geographical area.
