What specific type of evidence has solidified the understanding that white, black, and striped marlin are genetically distinct species?

Answer

Studies examining mitochondrial DNA and nuclear markers.

The resolution of confusion regarding the distinct species status of various marlins—white, black, and striped—has been achieved through rigorous contemporary genetic research. Modern molecular biology techniques, specifically the analysis of both mitochondrial DNA and various nuclear markers, provide definitive evidence confirming that these populations are genetically separate across their respective ranges. This molecular clarity moves beyond superficial physical similarities that previously caused researchers to group them ambiguously. Establishing these deep genetic boundaries has profound consequences for fisheries management, emphasizing that treating them as an amorphous single marlin group is scientifically inaccurate and detrimental to tailored conservation planning.
