How Does the Evolutionary Perspective Explain the Observation That Many

question 270

Multiple Choice

How does the evolutionary perspective explain the observation that many wild animals overeat when food is available?

• A)Weaker but rapidly multiplying species tend to overeat, which makes them less agile but less vulnerable to larger predators, who reproduce more slowly.
• B)Overeating helps build energy reserves for times when food may be scarce or unavailable.
• C)Overeating promotes an insulating layer of fat that traps body heat and allows the species to survive in a wider range of cold climates.
• D)Species that engage in overeating have evolved so that they have high basal metabolic rates and do not hibernate, qualities that utilize the excess calories and promote survival.
