The water in theYellowstone NationalPark hot springs shownhere is around 160°F(70°C). Biologistsassumed that no speciesof organisms couldlive in water aboveabout 130°F (55°C), sothey were surprisedto find several speciesof bacteria there, nowcalled thermophiles(“heat-lovers”). You’ve learned in this chapter how an enzymefrom one species, Thermus aquaticus, made feasible one of themost important DNA-based techniques used in labs today.Identify the enzyme, and indicate the value of its being isolatedfrom a thermophile. Suggest other reasons why enzymes fromthis bacterium (or other thermophiles) might also be valuable

Prokaryotic evolution

The term evolution means the gradual change or a transformation from a simple or primitive state to a complex or advanced state. Prokaryotic evolution is a concept that involves the evolution of the form and function of most primitive organisms (prokaryotes) through several stages and changes to form diverse life as a part of organic evolution.
