The dermal ridges on the surfaces of the palms and the fingers form dermatoglyphic patterns which are phylogenetically stable traits useful for evaluating interpopulation affinities and distinctiveness. In this study, these traits were investigated according to traditional methods among the Ogoni people of the Niger Delta region of Southern Nigeria, considering the uncertainties surrounding the people's historiography and the paucity of morphologic studies on the tribe. The evidences of finger whorl pattern frequencies, Total Ridge Count and palmar A-B ridge count indicate the close dermatoglyphic resemblance of the Ogoni to tribal populations of southern Ghana. These findings have implications as to the likely provenance of the Ogoni people, providing support to the traditionally view among the people that their ancestors are migrants from some tribe in southern Ghana, West Africa.
手掌和手指表面的皮嵴形成皮纹图案，这些图案是系统发育上稳定的特征，有助于评估群体间的亲缘关系和独特性。在本研究中，考虑到尼日利亚南部尼日尔三角洲地区奥戈尼人历史记录的不确定性以及该部落形态学研究的匮乏，按照传统方法对这些特征进行了调查。手指螺纹图案频率、总嵴数和手掌A - B嵴数的证据表明，奥戈尼人与加纳南部的部落群体在皮纹上极为相似。这些发现对奥戈尼人的可能起源具有启示意义，支持了该群体传统观点，即他们的祖先是来自西非加纳南部某个部落的移民。
