Paleontologist: Sifrhippus, a miniature horselike animal, lived about 56 million years ago. The average weight of Sifrhippus adults declined from 5.4 to 3.9 kilograms during a period of climatic warming that lasted about 175,000 years, then rose as the climate cooled again. The most likely explanation is that smaller mammals can shed heat more easily than larger ones-Sifrhippus must have adapted to the hot climate by shrinking because larger individuals would more often have died from overheating.
Which of the following would, if true, most strongly support the paleontologist's hypothesis?
A. The climatic warming shrank Sifrhippus habitats, and larger habitats can generally support larger animals.
B. Before the climate warming period, Sifrhippus went through several changes in average body size and weight that did not coincide with changes in climate.
C. Several species of small mammals went extinct during the period of climatic warming, while many larger species thrived.
D. Sifrhippus populations increased in numbers during the period of climatic warming, then decreased again as the climate cooled.
E. During the climatic warming period, Sifrhippus adults weighed more, on average, in populations in cooler habitats.
