 As we scuffle about our daily lives, experiencing various activity with varying degrees of awareness, our brains are scrambling to process the continual flow of sensory information. As the brain registers its interaction with the physical, material, external environment, brain cells are rapidly firing thousands of electrical impulses back and forth, communicating with many other nerve cells, and continually rearranging themselves according to the demands of external reality. Thus, the brain of an auto-mechanic, if surgically dissected and microscopically analyzed, would reveal a neuronal architecture representing the fashion in which that particular mechanic's nervous system adapted to the demands of auto-repair: we would find those areas of the brain most closely associated with strong problem-solving skills, spatial manipulation, and eye-hand coordination well-developed and rich in neuronal complexity, robust in electrical conductivity, and extensive in inter-neuronal associations, given an adequate specimen. Although such brain development occurs through an intimate relationship between genetics and experience, it is the specific, subjective, individualistic experience that manifests genetic potential. Thus, experience itself happens as a person's genetically defined biochemistry interacts with the external, physical universe. That said, we can play.

 Let's consider a hypothetical spectrum defined as encompassing everything between, and including, two extreme situations. On the one end of the spectrum, we find caveman, in any given environment, experiencing some reality. On the other end of the spectrum, we have modern man, in any given environment, experiencing some reality. The idea here is to employ models of individuals representing different genetic propensities, as defined via correspondingly opposite developmental contexts: cave-world or modern-world, in our example. With these models as the extremes, it may be helpful to establish a very average example, such as a fifth-century farmer, whose genetic makeup would represent genes affected by an environment somewhat more advanced than life in a cave, yet not quite as advanced as someone ordering online lyophilized urine for personal use.

 Looking, then, at a spectrum representing the overall, general, and continuous differences in genetic or biological ability, as a function of the hypothesized subject's brain development within different and unique social, political, and technological contexts, we focus specifically on the propensity of any given subject to perceive, process, and effectively utilize varying degrees of environmental complexity. Much like human filtration devices, our brains receive information from the environment, process information, and utilize the experience.
