Question 1

What happened during the Paleocene-Eocene Thermal Maximum?

Accepted Answer

The Paleocene-Eocene Thermal Maximum was an abrupt warming trend. Large-scale oceanic circulation was disrupted so that heat transfer from equatorial regions to the poles diminished or ceased. As a result, ocean waters became warmer, resulting in the extinction of many deep-water benthonic foraminifera.

Question 2

Discuss the development of the various groups of small mammals during the Cenozoic.

Accepted Answer

Small mammals include the insectivores, rodents, rabbits, and bats. These organisms have developed a variety of strategies to survive. Most of the insectivores, including the shrews, eat insects. Rodents represent a variety of organisms, including beavers. Part of their success is due to the fact that they can eat almost anything. Rabbits are gnawing animals that evolved separately from rodents. Bats adapted their forelimbs into wings.
