A certain species of sea otters lives off the coast of Alaska. Some have the ability to tolerate the colder waters farther north while others stay in the central coastal area. As a result of a large oil spill along the northern coast, most of the otters living in those colder waters die. Afterwards, the population of otters, in general, is now less tolerant of cold water. What is this an example of? A.) allopatric speciation B.) hybrid sterility C.) bottleneck effect D.) sympatric specia...
