Submitted: Jul 19, 2013; Accepted: Sep 3, 2013; Published: Sep 11, 2013 Abstract: The study of isotopic ratios of oxygen and carbon has gained importance to determine the origin of ore bearing fluids, carbon origin and also to determine the formation temperature of non-sulfide lead and zinc minerals. In order to determine the origin of fluids and carbon existing in zinc carbonate minerals in Ch...

W ith nearly two-thirds of the population afflicted, the Nuu-chah-nulth Indians of Vancouver Island in British Columbia have one of the highest rates of arthritis in the world. Often passed down family lines, the genetics of arthritis in this unique population was studied extensively during the 1980s by Richard Ward, now head of the Institute of Biological Anthropology at the University of Oxfo...

We introduce an approach to revealing the likelihood of different population histories that utilizes an explicit model of sequence evolution for the DNA segment under study. Based on a phylogenetic tree reconstruction method we show that a Tamura-Nei model with heterogeneous mutation rates is a fair description of the evolutionary process of the hypervariable region I of the mitochondrial DNA f...
