We are now dealing with a new ‘tree of life’. ’ is considered by Cracraft (2002) as one of the seven great questions for systematic biology, and is integral to many experiments we do. The species concept has been continually evolving and many of the recently tested ecological hypotheses and resulting conclusions are based on concepts of a species, derived from studies of organisms in which reproduction is normally sexual and individuals are easily defined (Cohan 2002). We must have an idea of our organism or OTU if we are to accept the soil as a living habitat and if we are to propose hypotheses at broader scales.
