Definitely directed evolution (1890-1926): the importance of variation in major evolutionary works by Theodor Eimer, Edward Drinker Cope, and Leo Berg

Description
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…

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.

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.

Death, Delight, and Destitution: What Sort of Epicurean was Palladas of Alexandria?

Description
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…

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.
