Implication

Molecular phylogeographic study reveals convergent evolution of long-beaked forms in common dolphins across eight regions, indicating independent origins rather than a single species.

Key Points

To resolve the evolutionary relationships, speciation patterns, and taxonomy of long-beaked and short-beaked morphotypes within the common dolphin genus Delphinus.
Assessed molecular markers in dolphin samples across eight distinct geographical regions.
Compared two morphologically classified long-beaked populations with established eastern North Pacific reference populations to evaluate genetic structure and monophyly.
Long-beaked dolphin populations exhibited high genetic differentiation rather than monophyly, indicating multiple independent evolutionary origins converging on the same morphotype.
Short-beaked populations demonstrated low genetic differentiation across broad geographic scales.
