Question

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 changed the allele frequency of the heat tolerant allele. After 2 years, the steam changed course again and the temperature in the pool returned to its original 89 deprees

Explanation / Answer

This story illustrate sympatric speciation or selection inthe population of thermal pool bacteria over time.Since, the change in allele fequency due to the variation in temperature may lead to emergence of new species(sister species) at same geographical area.
