In biology, many long held categorisations were finally abandoned because they were no longer productive, meaningful or they lacked an adequate evolutionary underpinning. The model for the evolution of metabolism outlined in this chapter explains why the terms primary metabolism and secondary metabolism should now be consigned to history. 

Taken together, these lines of evidence support the idea that evolution of metabolic pathways occurred after the introduction of atrazine (Shapir et al., 2007). Moreover, they may also indicate that certain use patterns of atrazine could potentially increase the ability of soil microorganisms to degrade the herbicide rapidly (Entry et al., 1995a Vanderheyden et al., 1997 Shaner and Henry, 2007).

In general, it is very likely that the ability to interact with other cell components has also been an important factor in the evolution of metabolism of living organisms. Thus, PolyP, which possesses a monotonic macromolecular, essentially linear, structure without any special features, could have become a somewhat unsatisfactory compound at a certain stage of cell development. The limited capacity of PolyP for precise and very specific interactions with other cellular metabolites resulted in an inconsistency with its function of coupling exo-and endoenergetic processes. Hence, ATP was selected for the above functions, because it has a much more specific, and therefore more readily recognized, structure. Moreover, ATP was capable of many other functions, which could not be performed by PolyP.
