BI-PEDAL MECHANISM (FOUNDATION SURFACE SET)
Recursive analysis, returning to the diametric intuition set delineates the foundation surface set constituted by the evolutionary/physiological propensity.
Conservative sub-set; and
Progressive sub-set.
The foundation surface set instantiates the bi-pedal mechanism of the normal species set. A human subject's phenotypic disposition is an inherent and characteristic genotypic function of the offensive domain. Hence, measures of the subject's ‘intensity of individuality’ may be estimated as a measure of the subject's appetite for and tolerance of risk.

Note a number of genetic traits differentiate subjects at the foundation surface set, and indeed, molecular genetics is yet to fully understanding quantitative trait linkages (QTL). However arguably, the predominant feature is testosterone and its resultant multifarious phenotypic expression. Whereas testosterone is involved in biological effects that are: (a) reproductive (androgenic); or (b) non-reproductive (includes anabolic effects), its counterpart in the form of estrogen, is characteristically defensive. That is, it is known that estrogen mediates learning and memory functions and also enhances cognitive processes. The brain can produce significant levels of estrogen and brain tissues possess ER-B (1).
The genetic germ-line verifies the male sex as an evolutionary strategy toward greater genetic independence.
