Why are scientists so interested in extremophiles?

Answer 1

Extreme environments have been useful to scientists in inventing PCR. It was in an extreme environment like the geysers of Yellowstone that a scientist discovered that a bacteria was living in the extremely hot water and yet still could function. Before PCR we knew we could separate a strand of DNA by heating it, but there was no polymerase to duplicate it that would work at such a high temperature. The bacteria in the hot water had a polymerase that would. So now scientists use that to do PCR and create many copies of DNA.
