Kawada, a co-author of this study, has been interested in “Techniques du corps; Technique of the body”, which means the usage of the human body observed in common within a ethnic group but differently among groups, and which may be decided by the nature around and their culture. He has been studied it with a point of view of morphological and functional biology, ecology and culture in the field of West Africa, France and Japan. He has been investigated the reason of the peculiarity of techniques of the body among West African compared with French and Japanese in ecological and cultural condition. But he could not discuss it biologically for lack of research about biological condition. In this study we measured Bamanan-Fulbe people in Republic of Mali who live on the savannah and Yoruba people in Federal Republic of Nigeria who live in the tropical rain forest with the anthropometrical method for basic data to discuss it biologically. We measured also Japanese as a comparison.
The result indicates that the figure of Bamanan-Fulbe people is tall and slender and in case of Yoruba people small and little bit fat. Their extremities are longer than that of Japanese. But we can easily explain this phenomenon with neither Bergmann's rule nor Allen's rule.
The bending posture which is well observed in Bamanan-Fulbe people indicates a typical form commonly. This form is defined as a extreme anteversion of the pelvis, the straight thoracic and lumbar spine, and the lordosis at the cervical spine. This form is not observed among Japanese. This typical form might be caused by the well stretched hamstrings, which are made by a sitting posture with thrown-out legs observed in common in Bamanan-Fulbe people.
