However, data from mtDNA sequencing suggested the opposite in that the larger body structure is primitive compared to the small body structure. The variance between the evolutionary histories determined by each form of evidence demonstrates the value of employing a comparative approach to generate an accurate phylogeny of Sphyrna. This research is relevant to my interest in the genus Sphyrna because the author is performing an extensive phylogenetic analysis of hammerhead shark species that can accurately represent their evolutionary history, as well as offer an explanation to their unique head
