Eumetabola is an unranked
clade of

. Two large unities known as the
Paurometabola and Eumetabola are probably from the
adelphotaxa of the

after exclusion of the
Plecoptera. The monophyly of these unities appears to be weakly justified.
Eumetabola has the highest number of species of any clade. According to a
phylogenetic analysis
In biology, phylogenetics (; from Greek φυλή/ φῦλον [] "tribe, clan, race", and wikt:γενετικός, γενετικός [] "origin, source, birth") is the study of the evolutionary history and relationships among or within groups o ...
, the Eumetabola clade originated 390-350 million years ago, in the
Late Devonian.

Phylogeny
The phylogeny of Eumetabola is shown in the
cladogram
A cladogram (from Greek ''clados'' "branch" and ''gramma'' "character") is a diagram used in cladistics to show relations among organisms. A cladogram is not, however, an evolutionary tree because it does not show how ancestors are related to ...
