The Genetic Gods: Evolution and Belief in Human Affairs

John Avise provides a assessment of up to date molecular biology that's rather available to the 'lay' reader with a few earlier publicity to the final sector of evolutionary-genetics. The discussions are a little bit philosophically charged (i. e. they don't stay unavoidably technical) and comment on social, emotional, and theological matters too.

Sample text

In an evolutionary context, to attempt to understand psychopathology only Evolution and Psychopathology 15 underscores the same human bias of the observer regarding what is normal, healthy, or functional. The bias is again entangled in ideas pertaining to the centrality of culture (or the symbolic) for determining what constitutes normal, abnormal, or pathological behavior. But the bias is reflected in a somewhat different form. An evolutionary interpretation of psychopathology requires a frame of reference rooted in the phylogeny of human behavior.

Finally, does the individual showing psychopathology act and communicate with awareness of it? This is the axiom of personal insight. Given these four generalizations about psychopathology, one can make six claims about its evolution, each of decreasing scope. These are the following: 1. Varieties of psychopathology are found in the naturally occurring social psychological behavior of our evolutionary ancestors—which encompass the last common ancestor (LCA), Australopithecine, Homo erectus or related Homo, Archaic humans like the Neanderthals, and/or Homo sapiens sapiens—that is designed to promote fitness, adaptability, well-being, and welfare.

On the other hand, the individual may be neglected, shunned, expelled, or perhaps even attacked 16 ORIGINS OF PSYCHOPATHOLOGY and slain. In some instances, psychopathological behavior in an organism would likely cause its failure to thrive as a functioning member of the group. In contemporary biological psychiatry, psychopathology is often equated with a brain-related physical-chemical “lesion” that produces abnormal mental processes and behavior. This has limitations from an evolutionary standpoint.
