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 fromoverheating.
The paleontologist's hypothesis is thefollowing:
