Uberon Homology note : A comparative anatomical approach reveals three apparent morphotypes of the cecal
appendix, as well as appendix-like structures in some species that lack a true cecal
appendix. Cladistic analyses indicate that the appendix has evolved independently
at least twice (at least once in diprotodont marsupials and at least once in Euarchontoglires),
shows a highly significant (P 0.0001) phylogenetic signal in its distribution, and
has been maintained in mammalian evolution for 80 million years or longer.[well established][VHOG];
