Question

The second paragraph in the passage serves primarily to (A) outline the signifi cance of the 1981 discovery of conodont remains to the debate concerning the development of the vertebrate skeleton (B) contrast the traditional view of the development of the vertebrate skeleton with a view derived from the 1981 discovery of conodont remains (C) contrast the characteristics of the ostracoderms with the characteristics of earlier soft-bodied vertebrates (D) explain the importance of the development of teeth among the earliest vertebrate predators (E) present the two sides of the debate concerning the development of the vertebrate skeleton

Answer 1

(E) present the two sides of the debate concerning the development of the vertebrate skeleton

Step-by-step explanation:

In the paragraph, the author talks about two sides of view in the subject of vertebrates evolution. On one hand, he/she says that the first idea of vertebrates development is that the skeleton evolved as a defensive character and that many researchers rely on soft-bodied vertebrates to conclude it. On the other hand, he/she says that other researchers postulate that some vertebrate features (as paired eyes and adaptation in some muscles) could not have evolved if the first vertebrates were not depredators.
