This thesis began as an investigation into evolution of the platypus family (Ornithorhynchidae, Monotremata), now known from both Australia and South America. The thesis broadened its scope with inclusion of non-ornithorhynchid Mesozoic monotremes from Lightning Ridge, NSW. This change in direction brought an unexpected result: a fossil mammal from Lightning Ridge investigated for this thesis (presumed to be monotreme: Flannery et al., 1995) appears to be a new and unique type of mammal. Specimens were procured through Queensland Museum (Riversleigh material); Australian Museum (Lightning Ridge material); and Museum of Victoria and the South Australian Museum (fossil ornithorhynchids). Specimens were examined under a light microscope and scanning electron microscope; specimens were photographed using light photography and a scanning electron microscope; and illustrations and reconstructions were done with a camera lucida microscope attachment and photographic references. Parsimony analysis utilised the computer programs PAUP and MacClade. Major conclusions: 1) analysis and reconstruction of the skull of the Miocene platypus Obdurodon dicksoni suggest this robust, large-billed platypus was a derived northern offshoot off the main line of ornithorhynchid evolution; 2) the well-preserved skull of Obdurodon dicksoni shows aspects of soft anatomy previously unknown for fossil ornithorhynchids; 3) two upper molars from Mammalon Hill (Etadunna Formation, late Oligocene, central Australia) represent a third species of Obdurodon; 4) the South American ornithorhynchid Monotrematum sudamericanum from the Paleocene of Argentina is very close in form to the Oligocene-Miocene Obdurodon species from Australia and should be considered congeneric; 5) a revised diagnosis of the lower jaw of the Early Cretaceous monotreme Steropodon galmani includes the presence of two previously undescribed archaic features: the probable presence of postdentary bones and a meckelian groove; 6) morphological evidence is presented supporting a separate family Steropodontidae; and 7) analysis of new fossil material for Kollikodon ritchiei suggests that this taxon is not a monotreme mammal as originally identified but is a basal mammal with close relationships to allotherian mammals (Morganucodonta; Haramiyida). Kollikodon is provisionally placed as basal allotherian mammal (Allotheria sensu Butler 2000) and is unique at the ordinal level, being neither haramiyid nor multituberculate. A new allotherian order ??? Kollikodonta ??? is proposed.

PROBLEMS INVESTIGATED:This thesis responds to a significant gap in modern Greek literary scholarship in relation to the Darwinian, post-Darwinian and other evolutionary theories and ideas in the works of Greek writers. My preliminary investigations show that there have been Greek writers who were influenced by Darwinian ideas. However, histories of modern Greek literature do not include Darwinism as a distinct influence in its own right, instead it only appears within the Greek naturalist school of the late 19th century; even when they discuss naturalist works influenced by evolutionary thought. This thesis primarily examines the Darwinian and post- Darwinian influence in select writings of Grigorios Xenopoulos in the period from 1900 to at least 1930. In doing so it attempts to reassess the status of these works and to argue for their importance in the context of other Greek and non-Greek literature. PROCEDURES FOLLOWED: This thesis takes on a cross-disciplinary approach drawing on the histories of science and of literature, on the biological sciences and other sciences. So as to establish a context for Xenopoulos' work, I discuss the themes and issues associated with evolutionary ideas and draw on Greek and non-Greek writers from the 19th century first wave of Darwinism to the first decades of the twentieth century. GENERAL RESULTS: I am able to document that while there appears to have been a general delay in the transmission of Darwinian ideas to Greek creative writers, certain themes in their writings arise, responding to Darwinism, which are common to those of non-Greek writers. While there are differences in the treatments of these themes amongst writers, there are a number of main issues which arise from them which include class, gender and race, and are shown to be important in Greek society at the time. In addition, the direct implications of Darwin's theory of evolution are debated in Greece by science and religion, and are discussed in the writings of Xenopoulos and his peers. MAJOR CONCLUSIONS: My examination of responses to Darwinism by Xenopoulos in the context of other Greek and non-Greek writers aims, firstly, to emphasise the importance of Xenopoulos and his work as a key literary influence in Greek society at the time; and secondly, to play a part in bringing modern Greek literature into the mainstream of European culture. The responses to Darwinism in literature, fiction and non-fiction, past and present, encompass a fascinating and controversial field of investigation which, in view of our scientific knowledge today, continues to address issues such as the nature-nurture debate, creationism versus evolution and man's place in nature. Hence it is important that literary responses to the Darwinism of the late 19th and early 20th centuries in Greece be documented as a foundation for present literary responses.
