Molecular phylogenetic Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to ...

studies showed that Micractiniaceae was polyphyletic and that ''Micractinium'' was closely related to '' Chlorella''. Accordingly, ''Micractinium'' has been transferred to the family Chlorellaceae.
