Hierarchies

 

In biology, structures and functions occur across a hierarchy of size, extending from molecules to organisms.  These hierarchies occur largely as nested sets wherein a given hierarchy is part of another, but also contains many hierarchies of its own. 

The EBS database uses sixteen hierarchical levels to build a qualitative framework onto which quantitative data can be attached.  Building such an framework starts with a theoretical model that slowly gives way to the realities of the literature - as more and more data are added.
