Primary 31-gene mammal supermatrix and posterior-tree study; its completed 5,911-species trees add unsampled species with explicit taxonomic constraints rather than direct sequence data.
Diprotodontia is represented as one constrained branch in a mammal-wide 31-gene phylogenetic framework, but many DNA-missing species in the completed trees were added by taxonomic constraints; the result is not direct sequence evidence for every diprotodontian or a fossil first appearance.
claim:taxon:diprotodontia:sampled-topologyProboscidea is represented in the mammal-wide phylogenetic framework by sampled living elephant lineages and taxonomically completed species placements, while extinct proboscideans require separate fossil evidence; the tree does not date the order’s origin.
claim:taxon:proboscidea:sampled-topologyRodentia forms a constrained higher branch in the mammal-wide 31-gene framework, but DNA-missing taxa in completed trees inherit explicit taxonomic placements; the analysis is not direct molecular evidence for every rodent or a fossil origin date.
