In yellowstone national park, there are dozens of spectacular thermal pools filled with very hot water that rises from deep underground. in each thermal pool, there is a community of microbes that create the spectacular colors we can see in them. these microbes are very temperature sensitive. between 1990 and 1997, the temperature in this pool was 89 degrees c. in 1997, a small, cool surface stream changed course and flowed into the pool, lowering the temperature by 7 degrees c. this significantly lowered the allele frequency of the heat tolerant allele. after 2 years, the stream changed course again and the temperature in the pool returned to its original 89 degrees, returning the allele frequency of the heat tolerant allele to its pre-1990 level. this story illustrate
