Developmental biologists' choice of subjects approximates to a power law, with no evidence for the existence of a special group of 'model organisms'

Arrows between journals depict changes of title, the span of each title being indicated by superscripts in the table. An arrow as the left-most character before the mention of a title shows that the journal is a developmentally-specilized relaunch of a previous journal too general to be included in this study (for example, Developmental Dynamics, a fully-developmental journal, is a continuation of American Journal of Anatomy, which included significant non-developmental content and was therefore exlcuded from this study).
