Paradigm lost? Scrutinizing the veracity of systems biologyU+2019s paradigm shift

While Kuhn elaborated his Structure of Scientific Revolutions mainly in reference to the history of physics, the concept 'paradigm shift' is also applied to current developments in the biological sciences. In casu, systems biology is promoted as representing a paradigm shift in the study of living organisms. After introducing systems biologyU+2019s practical ins and outs, we analyse how its identity is construed by claims stressing what is 'at the heart' of systems biology and what it purports to 'revolutionize'. These claims indicate that systems biologyU+2019s envisaged paradigm shift is about 'going beyond' molecular biology. The veracity of this paradigm shift rests on the perception of molecular biology as being atomistic and gene-centred. As this perception appears to be highly questionable, we conclude that systems biology forms an evolution within the range of normal science, rather than a truly Kuhnian paradigm shift. That today KuhnU+2019s legacy is handled loosely, and that an inappropriate use of the term 'paradigm shift' may indicate an 'accent shift' in the historiography of a scientific discipline, is hereby demonstrated. This leads to question whether the very concept of paradigm is outmoded to capture the dynamics in current biological sciences, in other words, is KuhnU+2019s paradigm 'lost'?
