Usage of phylogenetic terms according to field. Venn diagrams showing the usage of phylogenetic terms in articles from all three fields and those from outside the fields. (A) Shows in which field or fields a term was used during the year when it was first mentioned in our corpus; this demonstrates the origin of the term. (B) Shows usage of terms in the three fields (or outside the three fields) but measures usage across all years; this measures communication of the term between fields.
