Decapodiform evolutionary tree — Caption

The researchers employed multiple decapodiformes genomes along with a robust model of evolution and fossil evidence. Their evolutionary tree branches into 4 sections in the Cretaceous period, then sees no further branching until after the K-Pg extinction event, when rapid diversification occurred. Each final line end marks a different species. Of the major orders of decapodiformes, just oegopsida and spirulida remain in the deep ocean habitats of their ancestors.
