Three Styles in the Evolutiona

In the article by Eric Alden Smith entitled Three Styles in the Evolutionary Analysis of
Human behavior, Smith compares and contrasts three distinct approaches to the analysis of
human behavior through an evolutionary standpoint that have been developed recently.While
these three methods are different, Smith suggests that they be used not as an alternative to one
another, but rather as a group, since each looks at human behavior in different ways.
Thefirst method that Smith discusses is called evolutionary psychology or EP.This is
used to find out driving factors for human behavior and the selective forces such as environment
that influence them.It uses several assumptions called modularity, historicity, adaptive
specificity, and environmental specificity in hypothesis testing that is done in modern
populations with surveys or lab experiments.The next method is behavioral ecology or BE.
This method looks at behavioral strategies that influence subsistence and reproduction.EP
focuses on mating and sexual differences.And finally, Smith discusses the dual inheritance
theory or DIT which assumes culture is a system of inheritance that can be affected by multiple
forces.This method takes into consideration large scale cooperation and maladaptation.
Smith then goes on to present the arguments against these methods, usually brought up by
followers of a different method which come about as a result of their differences.He goes on to
say that complimentarity between the three styles can come from using like methods of
investigation.Smith sees that using all three methods is unison will yield a wider scope of understanding of our own selves.
