Mol Syst Biol. 1: 2005.0004 Demarcations of scientific fields have always followed either a conceptual breakthrough or have been a result of profoundly enabling technologies. Quantum theory and quantum mechanics revolutionized physics and engineering, but high‐energy physics is a discipline fundamentally enabled by the linear accelerator. Similarly, the discovery of the structure of DNA gave birth to molecular biology; structural biology is completely dependent on the technologies of chemical analysis albeit on complex molecules, and genomics was born out of high‐throughput DNA sequencing (arguably, the most important being sequencing by capillary electrophoresis). No naming‐committee was ever established to set the definitions for these …
