Timer The final Jeopardy answer is: C1 final Organisms evolve to survive their environments. When the environment changes, organisms that evolve quickly are the ones the survive. Organisms that do not evolve quickly do not survive. The fossil records show that sharks first appeared more than 400 million years ago. Dinosaurs appeared about 250 million years ago and became extinct about 65 million years ago. What is one possible reason why sharks have not become extinct?
C1 final Sharks live in the ocean. It is possible that the ocean environment has not changed much since 400 million years ago, or at least not so much that sharks could not evolve to keep living there. Dinosaurs lived on land, Their environment must have changed so quickly that they could not evolve to match it, and they became extinct.
C2 $100 Why might a very old or rare fossil not be a good index fossil?
C5 $400 If you were a scientist who found a clamshell in the rock layers of a desert. What could you infer about the area’s environment in the past?
C5 $400 When the clam lived there the environment was wet. Could have been a sea.
C5 $500 Why do scientists sometimes have trouble knowing the age of sedimentary rock layers?
C5 $500 Earthquakes and volcanic eruptions disturb the layers, and wind and water wear away some layers and deposit new ones.
