Question

can we use recent molecular tools to identify and classify organisms

Answer 1

Bacterial taxonomy based on phenotypic properties has encountered several problem ; many organisms grow to poorly under laboratary conditions to be studied : the same phentypic property often arises independently in more than one branch of a phylogenetic sometimes become unwidl

Answer 2

The science of classification of bacteria is called bacterial taxonomy. Bacterial taxonomy (G: taxis = arrangement or order, nomos = law or nemein = to distribute or govern), in a broader sense, consists of three separate but interrelated disciplines: classification, nomenclature, and identification.

Classification refers to the arrangements of bacteria into groups or taxa (sing, taxon) on the basis of their mutual similarity or evolutionary relatedness.
