This dissertation shows that the central conceptual feature and explanatory motivation of theories of evolutionary directionality between 1890 and 1926 was as follows: morphological variation in the developing organism limits the possible outcomes of evolution in definite directions. Put broadly, these theories maintained a conceptual connection between development and evolution as inextricably associated phenomena. This project develops three case studies. The first addresses the Swiss-German zoologist Theodor Eimer's book Organic Evolution (1890), which sought to undermine the work of noted evolutionist August Weismann. Second, the American paleontologist Edward Drinker Cope's Primary Factors (1896) developed a sophisticated system of inheritance that included the material of heredity and the energy needed to induce and modify ontogenetic phenomena. Third, the Russian biogeographer Leo Berg's Nomogenesis (1926) argued that the biological world is deeply structured in a way that prevents changes to morphology taking place in more than one or a few directions. These authors based their ideas on extensive empirical evidence of long-term evolutionary trajectories. They also sought to synthesize knowledge from a wide range of studies and proposed causes of evolution and development within a unified causal framework based on laws of evolution. While being mindful of the variation between these three theories, this project advances "Definitely Directed Evolution" as a term to designate these shared features. The conceptual coherence and reception of these theories shows that Definitely Directed Evolution from 1890 to 1926 is an important piece in reconstructing the wider history of theories of evolutionary directionality.

During the 1960s, the long-standing idea that traits or behaviors could be

explained by natural selection acting on traits that persisted "for the good of the group" prompted a series of debates about group-level selection and the effectiveness with which natural selection could act at or across multiple levels of biological organization. For some this topic remains contentious, while others consider the debate settled, even while disagreeing about when and how resolution occurred, raising the question: "Why have these debates continued?"

Here I explore the biology, history, and philosophy of the possibility of natural selection operating at levels of biological organization other than the organism by focusing on debates about group-level selection that have occurred since the 1960s. In particular, I use experimental, historical, and synthetic methods to review how the debates have changed, and whether different uses of the same words and concepts can lead to different interpretations of the same experimental data.

I begin with the results of a group-selection experiment I conducted using the parasitoid wasp Nasonia, and discuss how the interpretation depends on how one conceives of and defines a "group." Then I review the history of the group selection controversy and argue that this history is best interpreted as multiple, interrelated debates rather than a single continuous debate. Furthermore, I show how the aspects of these debates that have changed the most are related to theoretical content and empirical data, while disputes related to methods remain largely unchanged. Synthesizing this material, I distinguish four different "approaches" to the study of multilevel selection based on the questions and methods used by researchers, and I use the results of the Nasonia experiment to discuss how each approach can lead to different interpretations of the same experimental data. I argue that this realization can help to explain why debates about group and multilevel selection have persisted for nearly sixty years. Finally, the conclusions of this dissertation apply beyond evolutionary biology by providing an illustration of how key concepts can change over time, and how failing to appreciate this fact can lead to ongoing controversy within a scientific field.

The purpose of this paper is to explore what can broadly be described as the "American cultural narrative" by investigating and analyzing a particular element of American culture, the tragic play. In this paper, fifth-century Athenian and twentieth-century American tragedies are placed side by side, investigated, and analyzed with the hope of discovering aspects of the genre that are unique to American playwrights and might teach us something about the way in which we, as Americans, are separated culturally from others. The paper begins by analyzing the nature of the tragic genre before detailing how it has played a similar role here in the United States as it played in fifth-century Athens. Then, by analyzing primary texts, I seek to identify those unique aspects of the American form of the genre that reveal new insight into the American cultural narrative. The paper concludes by suggesting that the greatest insight that the tragic genre has to offer is that personal redemption and individualism are unique to American tragedy, suggesting that they might be unique aspects of the American cultural narrative.

Within the vast array of classical literature, many authors still have not been thoroughly examined. Among these, Palladas of Alexandria, a prominent epigrammatist in the Palatine Anthology, seems to import Epicurean themes. Based on the content and motifs of his poetry, I argue that Palladas leaned on Epicurean philosophy as presented in Lucretius's De Rerum Natura to salvage pagan identity in the midst of Christianity's increased popularity.

This paper looks at the impact sorority life has on the collegiate women at Arizona State University. Much of the content widely available regarding members of the Greek community is relatively negative and describes these organizations through a critical lens. Finding this content to be contrary to that of my own experience, I sought to analyze the effects the community had, specifically the effects of the sororities and sorority women at Arizona State University. The analysis began with a thorough review of the history of fraternities and sororities, as well as a short overview of the history of feminism. Through the examination of this data, it becomes clear that the foundations of sororities are directly correlated with feminist aims and the feminist movement. After completing a review of their foundation, a trifold analysis of today's sororities was conducted. First, eight studies on the impact of the fraternal and sororal organizations on their members were reviewed, compared, contrasted. Next, a comprehensive survey was sent out to the Arizona State sorority members receiving 273 responses that were analyzed both holistically and from specific angles. Lastly, a brief follow-up interview of 25 of those 273 women was done in order to get more in depth responses and opinions from the women in this community. Combining the knowledge and results garnered from the literature review, survey, and interviews, it can be concluded that contrary to popular media, sorority life, for the most part, does in fact empower the women within it and provide a beneficial impact to both the member and the community at large.

This analysis aimed to understand how and why certain representations of fraternity and sorority life are consistently used in media texts. Throughout this thesis I analyzed various media including films, a television series, a documentary, and coverage of a news story and found that fraternity and sorority representations reinforce different social issues. Additionally, this thesis discusses how fraternities and sororities are framed in the media texts as institutions which force members to abide by larger societal norms and gender roles. Stigmas and social issues surrounding fraternity and sorority life including hazing, violence, and toxic masculinity, femininity and feminism, diversity and racism, and partying, power and misogyny are the focus of many of the media used in this study. This thesis analyzed how media use these topics to generalize representations of fraternity and sorority life members and to perpetuate normalized gender roles and dominant narratives about race and sexuality.
