9. What is known scientifically about transitional forms in the fossil record?A) Their occurrence is predicted by special-creation (“Ford-Mustang-type”) “catastrophist” B) They are not observed.C) They provide complete records of every fossil lineage.D) They are found frequently for those general types of living things (such as shelly shallow-E) They conclusively provide the genetic linkage between Coke and Pepsi.models of the history of life, but not by evolutionary theory.marine creatures) that commonly produce fossils, but are not found as frequently for other general types.
Feedback: “Ford-Mustang-type” “catastrophist” models postulate many creations lacking transitional forms. Genetic links between Coke and Pepsi have not been established in the fossil record. But, transitions are known commonly from commonly fossilized lineages, and less commonly from less-commonly-fossilized lineages.Points Earned: 1.0/1.0 Correct Answer(s):D10. The extinction of many types of dinosaurs occurred about:11.
The picture above shows a beautiful specimen of Araucarioxylon arizonicum, a fossil tree from theMesozoic rocks of Petrified Forest National Park. Based on the discussions of evolution in the class materials, it is likely that:today.12.
Examine the two pictures above, labeled I and II. They are from the same sediment core collectedin sea-floor muds from beneath the Atlantic Ocean off the coast of South Carolina. (The pictures are scanning electron micrographs by Brian Huber of the Smithsonian Institution, and the scale is the same on both, as shown at the bottom of each.) One picture shows a sample from just below the unique layer marking the extinction that killed the dinosaurs, and the other picture shows a sample from just above that unique layer.
