1)We often explain our behavior in terms of subjective feelings, motives, or reasons, but evolutionary explanations are based on reproductive fitness.  What is the relationship between the two kinds of explanation?  For instance, is a human explanation for behavior, such as “falling in love,” incompatible with an evolutionary explanation?  

2)Many people regard the rapid population growth of less industrialized countries as our most serious environmental problem.  Others think that the population growth in industrialized countries, though smaller, is actually a greater environmental threat.  What problems result from population growth in less industrialized countries?  In industrialized nations?  Which do you think is the greater threat? Why?  

3)In Batesian mimicry, a palatable species gains protection by mimicking an unpalatable one.  Imagine that individuals of a palatable, brightly colored fly species are blown to three remote islands.  The first island has no predators of that species; the second has predators but no similarly colored, unpalatable species; and the third has both predators and a similarly colored unpalatable species.  Predict what might happen to the coloration of the palatable species on each island through evolutionary time if coloration is a genetically controlled trait.  Explain your predictions.  

4)There are vast stores of organic matter in the soils of northern coniferous forests and tundra around the world.  Suggest an explanation for why scientists who study global warming are closely monitoring these stores.
