An example of this is the concern to not take absence of evidence as evidence of absence. Further to this we are aware in each archaeological situation there is a chance that we may only ever discover a handful of pieces to the puzzle. It is in this current setting that we are becoming increasingly careful of our interpretations of negative evidence and of how preservation levels affect a record and how it is researched. The merits of investigating sites and landscapes that are yet to produce hominin fossils are being acknowledged. In the spirit of taking advantage of this current state of affairs, it is interesting to ask the question what can ‘non-archaeological’ sites or archaeologically “sterile” landscapes (as in those that are yet to produce signals of hominin presence), or more in general, negative evidence - tell us, if anything, about hominin biogeographic range edges? To investigate this, I ask the question could the north-western edge of the Neandertal biogeographic range as we now think we know it, ever have been extended westwards, into Ireland? There is evidence of a Neandertal presence in Wales, at 230kya, while the first recorded human presence in Ireland is at 12,5kya only. The likelihood of a former Neandertal presence in Ireland is investigated here. The question is approached three fold and focuses on 1) the available pathways to Ireland, 2) the possibilities for a hominin presence in terms of the associated environments and 3) the preservation of Pleistocene deposits which might have encased traces of Pleistocene hominin activities. Britain’s human occupation history is discussed in terms of the location of a source population and possible routes to Ireland via the Irish Sea. Environmental reconstructions relay a climate and environment that is clement at times and one that was capable of supporting a range of mid- to large-sized mammals. Following glacial events some species of flora and fauna were able to recolonize the area. Repeated successful colonization by a variety of mammals has led to suggestions that hominins could have colonized the island too. Severe and repeated glacial action however has removed the majority of Pleistocene deposits from Ireland, leaving the record damaged and extremely limited, and such suggestions difficult to test. At first glance the interpretation of the absence of Neandertal traces in Ireland is not a clear cut issue. There is an available source population, a range of species have colonized and recolonized the area and there is an environment that at times is far from harsh. Leaving Neandertal preference or lack of necessity to one side, the evidence as it stands does not give a definitive reason that their range could not have, even briefly, extended westwards into Ireland. The lack of a Neandertal signal could be put down to an issue of tolerances and preferences or to the lack of preserved sediments and research. This study concludes however that the physical barrier of the Irish Sea appears to be the cause of the absence of a Neandertal presence in Ireland, further palaeogeographic reconstructions of the Irish Sea as well as fieldwork need to be undertaken to test this interpretation in the future. This thesis highlights the difficulties of investigating areas with extremely limited evidence and damaged archaeological records but also gives reasons why we should do it anyway.Show less
