Systems Biology
Systems biology gained prominence in the early 21st century with advances in omics technologies and computational modeling. The field was influenced by the work of Ludwig von Bertalanffy, who developed general systems theory, and Hiroaki Kitano, who promoted the integration of biology and engineering. The establishment of initiatives like the Systems Biology Markup Language (SBML) and the International Society for Systems Biology (ISSB) further advanced the field.
