That is, both evolutionists and creationists tend to believe that Elementary, middle, and secondary school teachers may accepting evolutionary theory will result in a greater experience considerable unease when teaching evolution ability to justify or engage in racist or selfish behavior, in the context of the Earth or life sciences (Griffith and and will reduce people's sense of purpose and Brem, in press). Many factors may contribute to their self-determination. Further, Griffith and Brem (in press) discomfort, including personal conceptualizations of the found that in-service science teachers frequently share evolutionary process - especially human evolution, the these same beliefs and to avoid controversy in the most controversial aspect of evolutionary theory. classroom, the teachers created their own boundaries in Knowing more about the mental representations of an curriculum and teaching practices. evolutionary process could help researchers to There is a historical precedent for uneasiness around understand the challenges educators face in addressing evolutionary theory, particularly given its use to explain scientific principles. These insights could inform and justify actions performed in the name of science. educators of alternative methods in providing support Guthrie (1998) suggested examples of gross misuse of and assistance. In this study, we examined pre-service science related to an exploitation of the principles and teachers' conceptual representations of an evolutionary language used to describe evolution: the "Kallikak bad process through their personal narratives of evolution seed" philosophy of human reproduction; Tuskeegee for an imaginary humanoid species on a far-off planet. non-consented research on Black men; government The imaginary creature participants described tended to sanctioned sterilizations performed in prisons and resemble humans in both form and evolutionary history. mental institutions; and intelligence testing used to The narratives had a tendency to link evolutionary extend "racially inferior" labels to Native Americans and changes with social and moral consequences. Those Mexican Americans. whose narratives closely paralleled human evolution Post-World War I American was marked with also seemed to have difficulty envisioning evolutionary disillusionment and fear regarding human progress in changes that would take the species past current human the face of violence and worldwide conflict (Moore, 1998, development and into their evolutionary future.

American and European biologists, alike, believed connection among social and moral issues, evolution, early interpretations of Darwin's concept of natural and difficulties envisioning the future may provide selection was distorted by the German militarism to important clues into pre-service teachers' promote and create war (Farber, 1994). Moore claimed conceptualizations of human evolution. Addressing that post-WWI American culture developed a personal barriers and misunderstandings that might "...nostalgia for the relative simplicity of prewar life, impede geoscience education may become an effective combined with a perceived decline in morality [that] led tool for teaching scientific principles. many people to rely increasingly on their religious faith for stability and comfort" (p. 487). The 1925 Scopes trial exemplifies the public INTRODUCTION treatment of evolutionary theory following the first World War whereby human evolution became tied to Few people remain indifferent about teaching ideas of evil, bigotry, morality, atheism, and images of evolutionary theory in America (Dennett, 1995). monkeys turning into man (Moore, 1998, 1999). The Research regarding the teaching and learning of atrocities committed by the Nazis during World War II evolutionary theory has focused heavily on student further stigmatized evolutionary theory in the public comprehension and misconceptions (Bishop and eye. Postwar America saw an even deeper resurgence of Anderson, 1990; Cobern, 1994; Dawkins, 1976; Demastes faith and morality, particularly by American et al., 1995; Moreland and Reynolds, 1999; Piburn et al., fundamentalists, who turned to education and politics to 1986; Zimmerman, 1987), or on curricular and policy strengthen the image of morality. Today, fears of issues (Shankar and Skoog, 1993; Skoog, 1984). Less abandoned faith, unethical scientific practices, concern attention has been given to the social and personal for human morality, and a loss of purpose continue to be consequences that arise from the complex and coupled with evolutionary theory (Brem et al., 2003; controversial relationship between evolutionary theory Dawkins, 2003; Gitt, 1995; Ham, 1998). and issues such as racism, social Darwinism, eugenics, Wolpoff and Caspari (1997) re veal that evo lu tion ary and other ethical dilemmas (Farber, 1994; Franklin, 1991; bi ol ogy is fre quently cat e go rized as the study of hu man Moore, 1998, 1999; Griffith and Brem, 2003; Moreland race or hu man types.
