They can compare the molecular structure of a particular molecule in two species, and the number of differences which exist can be plotted against the rate at which the molecule undergoes neutral substitutions (which has already been established). They live in anaerobic environments such as sewage treatment plants, and make methane. The classification is created by humans instead of being defined by nature. What are the 3 genetic causes of variation? They were extermophiles, and conditions on early Earth were very hostile. They can be beneficial if the environment changes; the better the adaptation, the more likely the organism will be to survive and the more likely the variation will be passed on. Many other taxa can be used to provide alternative contexts, however. Topic 5: On the Wild Side 5.18 Topic 6: Immunity, Infection and Forensics 6.3. How can intraspecific variations be useful?
