Implications Of Late Pleistocene Climatic Change On The Morphological Variations Of The Neanderthal, Dawn Marie Bradley
Implications Of Late Pleistocene Climatic Change On The Morphological Variations Of The Neanderthal, Dawn Marie Bradley
Geosciences Theses
In this research, the relationship of climatic changes between 130k to 28k years BP to concurrent morphological variations in Neanderthals was tested. Traditional anthropological studies attribute robust Neanderthal morphological traits as an adaptation to a cold environment. A database of previously completed terrestrial paleoclimatic reconstructions in Europe and the Mediterranean was compiled and used to create a series of GIS-generated timeslice maps. Regional climatic conditions were then related to changes in Neanderthal appearances, morphology and disappearances as evident in the archaeological record. To establish climatic conditions, existing studies were compiled from two regions: Europe and the Mediterranean. The European data …
Continuous Late Pleistocene Paleoclimate Record From The Southwest African Margin: A Multi-Proxy Approach, Julia Keegan Shackford
Continuous Late Pleistocene Paleoclimate Record From The Southwest African Margin: A Multi-Proxy Approach, Julia Keegan Shackford
Geosciences Theses
Late Pleistocene sediments recovered from ODP Leg 175, Site 1085 are used to generate a high-resolution (500 yr) record of continental climate change in Southern Africa. The location of Site 1085, the SW African continental slope, provides a continuous hemipelagic section with a significant terrigenous component. Terrigenous sediments are transported via fluvial and/or eolian transport mechanisms with MIS 1 being dominated by eolian transport. Analyses, including grain-size, color reflectance, biogenic sediment geochemistry (%CaCO3, %TOC, and C/N), bulk sediment geochemistry, and clay mineralogy, are used to identify continental climate conditions in southern Africa. Analyses indicate glacial/interglacial variation. Median grain-size peaks are …
