[S]ystems biology is the study of the behavior of complex(Marc W. Kischner, “The meaning of systems biology.” Cell
biological organization and processes in terms of the
molecular constituents. It is built on molecular biology in its
special concern for information transfer, on physiology for its
special concern with adaptive states on the cell and
organism, on developmental biology for the importance of
defining a succession of physiological states in that process,
and on evolutionary biology and ecology for the appreciation
that all aspects of the organism are products of selection, a
selection we rarely understand on a molecular level.
Systems biology attempts all of this through quantitative
measurement, modeling, reconstruction, and theory.
Systems biology is not a branch of physics but differs from
physics in that the primary task is to understand how biology
generates variation. … [T]he success of systems biology is
essential if we are to understand life; its success is far from
assured – a good field for those seeking risk and adventure.
