| None of the Triassic superfamilies of ammonites lived on into the Jurassic, but three new superfamilies appeared in the Early Jurassic. |
| The gene duplication event that gave rise to class I and class II knox gene superfamilies occurred before the divergence between bryophytes and spermatophytes. |
| The first group includes the molecule belonging to the species of the superfamilies Cavioidea and Chinchilloidea, which conserves the number of residues. |
| Many of the primitive characteristics retained in the larva are important in the classification of the suborders, superfamilies, and families. |
| In the Passeri alone, a number of minor lineages will eventually be recognized as distinct superfamilies. |
| On the basis of broad structural characteristics, amphibian antimicrobial peptides have been grouped into superfamilies, each being differentiated into various families. |
