I suggest the occurrence of many diseases is dependent upon the decline of DHEA which begins around 20-25 years of age and reaches very low levels in old age.  Also, it follows from my work, that many problems that are increasing with time in the United States and in the world are resulting from the "secular trend," which I suggest is due to the increase in percentages of individuals of higher testosterone and the negative effect that testosterone exerts on the availability of DHEA.  Disturbances in "dehydroepiandrosterone homeostasis" may be a significant source of morbidity and mortality.

Modern applications extends my work to modern humans.  “Modern humans” is a very broad area since it includes Homo sapiens from our origin in Africa through today.  Human evolution is ongoing and identifiable within current populations.

New Ideas and Research contains current research of relevance to this site.  This includes applications of my work to new research.  These explanations will both extend and revise my past work.  These interpretations will be moved to the other sections below as necessary.

Physiology and Pathology  is the broadest category.  This area contains many aspects of growth, development, and aging, as well as significant deviations from normal.  This concerns our individual lives or ontogeny.

Evolution  includes an examination of evolution primarily concerned with human phylogeny.  This extends from evolution of eukaryotic organisms to humans.

This site is intended to disseminate information generated from ongoing work I began in 1984.  Two works were produced in 1985: Evolution of Sociopathy in Western Civilization. A Philosophical Treatise followed by A Theory of the Control of the Ontogeny and Phylogeny of Homo sapiens by the Interaction of Dehydroepiandrosterone and the Amygdala, both copyrighted.  The original focus was narrow.  The scope has rapidly broadened simultaneously with increasing awareness of the explanatory usefulness of the primary ideas.  It is my hypothesis that selection for the androgens, dehydroepiandrosterone and testosterone, is directly linked to human evolution.  Evolution consists of ontogeny and phylogeny.
 
The information is divided into categories variously dealing with human ontogeny and phylogeny.  Since human ontogeny, the life of the individual, and phylogeny, the life of the species, are interdependent, my divisions are also not exclusive.  These categories are intended only as different entrances to a single explanation of human biology.  There is extensive overlap.  Periodically, new research will be included and discussed below.  (Click on the appropriate category below to access the page.)
