What is the Willi Hennig Society?
The Willi Hennig Society was founded in 1980 with the expressed purpose of promoting the field of Phylogenetic Systematics. Hennig’s idea that groups of organisms, or taxa, should be recognized and formally named only in cases where they are evolutionarily real entities, that is monophyletic, at first was controversial. It is now the prevailing approach to modern systematics.
The Hennig Society has a strong international character. It meets annually and the meetings usually alternate between North America and the rest of the world.
The journal Cladistics is the official publication of the Willi Hennig Society. It comprises a rich mixture of theoretical and empirical peer-reviewed contributions to phylogenetic systematics.
