My interest in the relationships between new evolutionary theory and Catholic theology has been prompted by the intellectual movement that has been called “sociobiology” or “evolutionary psychology.” Sociobiologists propose that, in addition to animal behavior, natural selection theory can explain human behavior, history, social interactions, even the faith and practice of the various Churches. Darwinism has shaped a worldview, or an hermeneutic through which human existence, history and activity can be understood. One of the underlying problems with classical Darwinian method is that certain ideological presuppositions both overrule observed evidence and interfere with otherwise good scientific thinking. However, evolutionary theory can help explain human behavior and historical development. This paper will thus survey some experimental work in relating theology to sociobiology. However, I am taking the experimental approach of exploring newer, or reformed, evolutionary thinking
