This conclusion has been supported not only by the degree of interrelation shown by different groups within the family compared with that found among the Leguminosae and their closest relations, but also by all the recent phylogenetic studies based on DNA sequences.
Este punto de vista reforzouse non só polo grao de interrelación que exhiben diferentes grupos dentro da familia comparados con aquel achado entre as leguminosas e os seus parentes máis próximos, senón tamén por tódalas recentes análises filoxenéticas baseadas en secuencias do ADN.
