Biohistory, and Biohistory: Decline and Fall of the West, both out now

The Biohistory books

Dr Jim Penman PhD has spent forty years developing a theory of history and society based around the concept that human social behavior has biological roots. Recent developments in the field of epigenetics, and a six-year research program commissioned through leading Melbourne universities, has confirmed and extended many of his ideas.

The theory has been published in two books: Biohistory: Decline and Fall of the West – purposefully aimed at the non-scientific community and Biohistory, a fuller academic text. Both have drawn critical acclaim and the support of notable figures from the academic community. The titles are published through Cambridge Scholars Publishing, a publishing house founded by researchers from the University of Cambridge, England.

“Biohistory offers an experimentally based approach to the study of temperament and how it acts as the underlying factor driving the course of history.  Temperament refers not only to the values of peoples but also to their character, stress levels, loyalty and reliability as revealed in their parenting, sexual, and economic behaviors. Biohistory is a book worth studying, testing, refuting and elaborating. ”

Dr. Ricardo Duchesne
Department of Social Science, University of New Brunswick Saint John
