Abstract

Despite genetic similarities between man and other anthropoids, the cognitiveabilities of man are distinct. Inaccessible and concealed external female genitals are one of the morphologicalcharacteristics distinguishing humans from other higher primates. External female sexual organs in subhumanprimates are visible and accessible in the habitual quadrupedal and occasional bipedal posture, whereasthese organs in the human female are inaccessible and concealed in any posture. A prospective consequenceof gradual bipedalism of hominids during evolution was a shifting of the external female genitals inan anterior direction. In the completely bipedal Homo sapiens, this resulted in the vulvo-cryptic phenomenon,i.e. concealed female genitals in humans. The unique morphology of the human female pelvis served asan obstacle to easy access of the male in the process of copulation, necessitating the female's consciousdecision for sexual intercourse. This circumstance might have created a psychological basis for femalepropellant psychosexual manipulation of the male as a natural consequence. Also, through the processof positive selection it could have formed a basis for linking reproductive success with the developmentof cognitive and emotional capacities. Female consent to copulation is a conscious and complex act thatwould be impossible without the involvement of highly developed emotional-cognitive and memoric brainsystems. Thus the extraordinary evolutionary strategy might imply a teleological link between concealedfemale genitals and the emotional-cognitive characteristics of man, creating a permanent promoter offurther development of emotional and cognitive brain systems with an impact on all domains of everydaylife.
