Coevolution of host and parasite

Webmorphological phylogenetics have had a profound influence and have shed new light on the very nature of host-parasite relations and their coevolution. Life cycle complexity, parasite ecology and the origins and evolution of parasitism itself are all underpinned by an understanding of phylogeny.
