What method is used today to classify organisms? - Answer Polyphasic taxonomy which classifies according to genotype, phenotype, and evolutionary (rRNA) reasons Identify the common characteristics of Deep-Branching Thermophiles - Answer 1. High mutation rate 2. Fastest doubling rates of all bacteria 3. Diverged the earliest from ancestral archaea and eukaryotes 4. Genomically, they are bacteria 5. Usually exist in very hot environments, such as hot springs Describe what makes bacteria ...
