Biology as the key science of the 21st century explores what life is and how it works, at all levels, from the molecule to the cell to the organism and to entire ecosystems. Not only the enormous bandwidth is noticeable, but also the fact that the different biology areas are becoming more and more interconnected. Molecular biologists also study genes in whole organisms, and environmental biologists also study the molecular basis of ecosystems. In biology studies at the University of Basel, students are prepared for research in contrast to biology lessons at the school. It is no longer just general knowledge, but in particular the acquisition of a deep, up-to-date and concentrated foundation of theoretical and practical knowledge of organisms and life processes.
