International Journal of Exercise Science 7(2) : 128-139, 2014. The Paleolithic (Paleo) diet is one modeled after the perceived food consumption of early human ancestors of the Paleolithic Era, consisting of mainly meat, fish, fruit, vegetables, eggs, and nuts. The purpose of this study was to examine the effects of a Paleo diet on blood lipids, including high-density lipoprotein (HDL), low-den...
The Checua site within Nemocón in the eastern Andean Region of Colombia has produced evidence of huntergatherer activities from 9500-8700 cal yr BP. The aim of this work was to analyze genetically the Checua group according to mitochondrial DNA HVR-I sequence data. Following strict criteria of authenticity for studies of ancient DNA, extracted DNA was amplified and sequenced for each of the hum...
The paper documents the use of a Digital Elevation Model (DEM) method to reconstruct paleochannels and the paleo-coastline during the Last Glacial Maximum (LGM) in the Central Eastern Adriatic area. We focused on the paleo-coastline and paleo-channels of the Neretva and the Cetina rivers, which were estimated from the 15’’ bathymetry available for the Adriatic Sea. While being aware of the limi...
The New World Arctic, the last region of the Americas to be populated by humans, has a relatively well-researched archaeology, but an understanding of its genetic history is lacking. We present genome-wide sequence data from ancient and present-day humans from Greenland, Arctic Canada, Alaska, Aleutian Islands, and Siberia. We show that Paleo-Eskimos (~3000 BCE to 1300 CE) represent a migration...
Abstract Far from studying only beings the past, Paleontology is a current science which can situate human existence in context of global environmental crisis before inequalities and socio-environmental conflicts occur Brazilian paleontological sites. Aiming to discuss possible connections between Environmental Justice, this essay arises survey on existing sites Minas Gerais. Stemming issues fo...
Geological history of oceanic islands can have a profound effect on the evolutionary history of insular flora, especially in complex islands such as Tenerife in the Canary Islands. Tenerife results from the secondary connection of three paleo-islands by a central volcano, and other geological events that further shaped it. This geological history has been shown to influence the phylogenetic his...
[1] In Deep Sea Drilling Program (DSDP) Hole 417D in the western central North Atlantic, dips of pillow margins measured in the upper and lower part of basement correlate with tilts predicted from paleomagnetic inclinations in the corresponding parts of the hole. A 40 westward dip of the seafloor around 417Dmatches the tilt predicted from inclinations and pillow margin dips in the uppermost lav...
The study of stable isotopes in fossil bioapatite has yielded useful results and has shown that bioapatites are able to faithfully record paleo-environmental and paleo-climatic parameters from archeological to geological timescales. In an effort to establish new proxies for the study of bioapatites, intra-tooth records of enamel carbonate stable isotope ratios from a modern horse are compared w...
The pattern and magnitude of glacier equilibrium-line altitude (ELA) lowerings in the tropics during the last glacial maximum (LGM) are topics of current debate. In the northern tropics, paleo-ELA data are particularly limited, inhibiting the ability to make regional and large-scale paleoclimatic inferences. To improve these records, nine paleo-glaciers in the Venezuelan Andes were reconstructe...
