Document Summary
Bacterial speciation: eukaryotes especially sexual (including all animals and plants) the definition is based on reproductive isolation makes them different biological species. The mutation that leads to this process that allows them to use this energy source would be the one that describes the specific ecotype. Used to write species definition in latin because it doesn"t change and english does. As of this year, jan 2012, you don"t have to write it in latin. Bacterial phylogeny long terminal branches and short internal branches: blue phyla most species identified in the gene bank utilize them in their species names (15 shown) Dna sequences closely related to bacteria than to archea. Ecological niche is more similar to thermophillic archea. Eg) thermus aquaticus thermophillic organism that is the source of the first taq polymerase dna for pcr. One of the first billion $ product of industrial microbiology.
