B. All trees alive today are completely unrelated to Araucarioxylon arizonicum. C. Some trees alive today are essentially identical to Araucarioxylon arizonicum. Evolutionary theory indicates that living things change from generation to generation, but that all living things are related. Consistent with this, Araucarioxylon arizonicum is recognizably similar to, yet different from, Araucaria trees such as monkey puzzle that are native to southern South America today. Points Earned: 1/1 Correct Answer: A Your Response: A 12 . The pictures labeled I and II show fossils from a sediment core collected from the floor of the Atlantic ocean, east of South Carolina. The sediment has not been disturbed by landslides or mountain building or other processes. The pictures were taken by Brian Huber, of the Smithsonian Institution, using a scanning electron microscope. The two samples in the sediment core were separated by the unique layer marking the extinction that killed the dinosaurs. Which is correct? A. II is older than the unique layer, and thus sat below the unique layer in the sediment on the sea floor. B. I is older than the unique layer, and thus sat below the unique layer in the sediment on the sea floor.

C. II is older than the unique layer, and thus sat above the unique layer in the sediment on the sea floor. D. I is older than the unique layer, and thus sat above the unique layer in the sediment on the sea floor. Before the impact, biodiversity was high, as shown in I, which includes fossils from below the unique layer and thus deposited before the meteorite hit. After the impact, most of the living types were killed, giving rise to the limited diversity seen in II from above the unique layer after the impact. Points Earned: 1/1 Correct Answer: B Your Response: B 13. The picture above shows: A. A sideways dinosaur track; the picture should be rotated ninety degrees clockwise to be right-side-up. B. An upside-down dinosaur track. C. Mud cracks. D. A sideways dinosaur track; the picture should be rotated ninety degrees counterclockwise to be right-side-up. E. A right-side-up dinosaur track.

This is a dinosaur track, from Dinosaur Ridge, and the dinosaur stomped down into the mud, so the track is upside-down; the instructional team used the power of modern computers to invert the picture. Points Earned: 0/1 Correct Answer: B 1. True or False: religion and science always disagree. A. True. B. False. Pope John Paul II said that the Catholic Church has no problem with evolution, and Baptist Jimmy Carter also supported evolution, so it is clear that religion and science can agree. Points Earned: 1/1 Correct Answer: B Your Response: B 2. The picture above shows: A. A sideways dinosaur track; the picture should be rotated ninety degrees counterclockwise to be right-side-up.
