greater understanding of psychopathology will be found in the
integration of genetic and evolutionary perspectives on adaptation
and function. Evolutionary theory proposes that adaptive traits
are reproduced more successfully than maladaptive ones. However,
some traits, while contributing to fitness in the ancestral environment,
may contribute to fitness no longer. This is known as mismatch
theory. Evolutionarily informed research into various “pathologies”
has yielded interesting results, some based on this theory. This
paper serves to distinguish between genetic and evolutionary perspectives
on psychopathology as well as to examine some recent research
on the selective forces that may be implicated in psychopathy,
anorexic behavior, and ADHD. We suggest that research into psychopathy
in general would benefit from an evolutionary perspective and
an examination of the assumptions behind past research.
all the facts of life, the most important is evolution. If
psychology is to take its legitimate place among the family
of life sciences, it must eventually integrate its basic theories
and facts with those of evolution. If we are to understand
abnormal behavior, we must do so in the context of a psychology
so conceived and so formulated.
