Molecular-based characterizations of Andean peoples are traditionally conducted in the service of elucidating continental-level evolutionary processes in South America. Consequently, “western” Andean population genetic variation is often represented in relation to “eastern” variation among Amazon and Orinoco River Basin populations. This west-east contrast in patterns of population genetic variation is typically attributed to large-scale phenomena, such as dual founder colonization events and/or differing long-term microevolutionary histories. However, alternative explanations that consider the nature and causes of population genetic diversity within the Andean region remain underexplored.

Here we examine population genetic diversity in the Peruvian Central Andes using mtDNA HVI and …

The Australian Barrineans And Their Relationship To Southeast Asian Negritos: An Investigation Using Mitochondrial Genomics, Peter Mcallister, Nano Nagle, Robert John Mitchell

Human Biology

The existence of a short-statured Aboriginal population in the Far North Queensland (FNQ) rainforest zone of Australia’s northeast coast and Tasmania has long been an enigma in Australian anthropology. Based on their reduced stature and associated morphological traits such as tightly curled hair, Birdsell and Tindale proposed that these "Barrinean" peoples were closely related to "negrito" peoples of Southeast Asia and that their ancestors had been the original Pleistocene settlers of Sahul, eventually displaced by taller invaders. Subsequent craniometric and blood protein studies, however, have suggested an overall homogeneity of indigenous Australians, including Barrineans. To confirm this finding and determine …
