Excavata

Until  recently this  assemblage was  less  well  supported than the  archaeplastida, but recent analysis that excludes rapidly evolving  taxa places them as a monophyletic super- group containing the  euglenozoa, heterolobosea, kinetoplastids, and  a recently erected phylum, the fornicata. The group includes many significant human and animal parasites, many of which have anaerobic or microaerophyllic lifestyles, and also the photosynthetic euglenids.
