Racial Experience As An Alternative Operationalization Of Race, Jada Benn Torres, Gabriel A. Torres Colón

Human Biology Open Access Pre-Prints

The study of human variation is central to both social and biomedical sciences; however, despite agreeing that variation is integral to the human experience, social and biomedical scientists diverge in how variation is theorized and operationalized. Race becomes especially problematic because it is a cultural concept that contains implicit and explicit understandings of how collective bodies differ. In this paper, we propose an operationalization of race that is attentive to both racial experience and human biological diversity—placing them within the same ontological sphere. Furthermore, we argue that this approach can more effectively advance antiracist pedagogy and politics.

We argue that …

Does Environmental Knowledge Inhibit Hominin Dispersal?, Colin D. Wren, Andre Costopoulos

Human Biology Open Access Pre-Prints

We investigate the relationship between the dispersal potential of a hominin population, its local scale foraging strategies, and the characteristics of the resource environment using an agent-based modeling approach. Wren et al. (2014) demonstrated that natural selection can favour a relatively low capacity for assessing and predicting the quality of the resource environment, especially when the distribution of resources is highly clustered. This also suggested that the more knowledge foraging populations had about their environment, the less likely they were to abandon the landscape they know and disperse into novel territory. The present study gives agents new individual and social …

Inference Of Cultural Transmission Modes Based On Incomplete Information, Bryan Wilder, Anne Kandler

Human Biology Open Access Pre-Prints

In this paper we explore the theoretical limits of the inference of cultural transmission modes based on sparse population-level data. We approach this problem by investigating whether different transmission modes produce different temporal dynamics of cultural change. In particular we explore whether the distributions of the average time a variant stays the most common variant in the population, denoted by t_max, conditioned on the considered transmission modes are sufficiently different to allow for inference of underlying transmission modes. We assume time series data detailing the frequencies of different variants of a cultural trait in a population at different …

Origins Of An Unmarked Georgia Cemetery Using Ancient Dna Analysis, Andrew T. Ozga, Raúl Y. Tito, Brian M. Kemp, Hugh Matternes, Alexandra Obregon-Tito, Leslie Neal, Cecil M. Lewis, Jr.

Human Biology Open Access Pre-Prints

Determining the origins of those buried within undocumented cemeteries is of incredible importance to historical archaeologists and in many cases, the nearby communities. In the case of Avondale Burial Place, a cemetery in Bibb County, Georgia, in use from 1820 to 1950, all written documentation of those interred within it has been lost. Osteological and archaeological evidence alone could not describe, with confidence, the ancestral origins of the 101 individuals buried there. In the present study, we utilize ancient DNA extraction methods to investigate the origins of Avondale Burial Place through the use of well-preserved skeletal fragments from 20 individuals …

Influence Of Changes In Political Barriers And Of Geographic Distance On Kinship Inferred From Surnames And Migration Data In Olivenza (Spain) And Surrounding Portuguese Areas, J. Román-Busto

Human Biology Open Access Pre-Prints

The existing relationship between human populations is a function of their migratory and genetic exchange which will be inversely proportional to the distance separating them. The effect of geographic distance on population structure may be estimated by means of isonymic methods which use information on the surnames present in a territory as an approximation to the distribution of allele frequencies. The objective of this study is to analyse whether the modification in 1801 of the political border in an area surrounding the town of Olivenza, which experienced a change of sovereignty from Portugal to Spain, has had noticeable influence on …

Mongolians In The Genetic Landscape Of Central Asia: Exploring The Genetic Relations Among Mongolians And Other World Populations, Jane E. Brissenden, Judith R. Kidd, Baigalmaa Evsanaa, Ariunaa Togtokh, Andrew J. Pakstis, Françoise Friedlaender, Kenneth K. Kidd, Janet M. Roscoe

Human Biology Open Access Pre-Prints

Genetic data on North Central Asian populations are underrepresented in the literature, especially autosomal markers. In the present study we use 812 single nucleotide polymorphisms that are distributed across all the human autosomes and that have been extensively studied at Yale to examine the affinities of two recently collected, samples of populations: rural and cosmopolitan Mongolians from Ulaanbaatar and nomadic, Turkic-speaking Tsaatan from Mongolia near the Siberian border. We compare these two populations to one another and to a global set of populations and discuss their relationships to New World populations. Specifically, we analyze data on 521 autosomal loci (single …

Hemochromatosis: Niche Construction And The Genetic Domino Effect In The European Neolithic, John M. Mccullough, Kathleen M. Heath, Alexis M. Smith

Human Biology Open Access Pre-Prints

Hereditary hemochromatosis (HH) is caused by a potentially lethal recessive gene (HFE, C282Y allele) that increases iron absorption and reaches polymorphic levels in Northern European populations. Because persons carrying the allele absorb iron more readily than non-carriers, it has often been suggested HFE is an adaptation to anemia. We hypothesize positive selection for HFE began during or after the European Neolithic with the adoption of an iron-deficient high grain and dairying diet and consequent anemia, a finding confirmed in Neolithic and later European skeletons. HFE frequency compared with rate of lactase persistence in Eurasia yields a positive linear …

Identification Of Whole Mitochondrial Genomes From Venezuela And Implications On Regional Phylogenies In South America, Esther J. Lee, D. Andrew Merriwether

Human Biology Open Access Pre-Prints

Recent studies have expanded and refined the founding haplogroups of the Americas using whole mitochondrial (mtDNA) genome analysis. In addition to pan-American lineages, a number of studies have identified specific variants that show higher frequencies in restricted geographical areas. In order to further characterize Native American maternal lineages and specifically examine local patterns within South America, we analyzed twelve maternally unrelated Yekuana whole mtDNA genomes from one village (Sharamaña) that include the four major Native American haplogroups A2, B2, C1, and D1. Our study proposes a reconfiguration of one subhaplogroup A2 (A2aa) that is specific to South America and identifies …

Microdemographic Determinants Of Population Recovery Among The Northern Ache, Jack D. Baker Jr, Kim Hill, A. Magdalena Hurtado, Adelamar Alcantara, Eddie Hunsinger, Webb Sprague

Human Biology Open Access Pre-Prints

A pattern of population crash and rapid recovery is a common feature of the pacification and settlement experience of the Indigenous Peoples of tropical South America. In spite of the obvious importance of these events to the demographic and anthropological sciences as a whole, as well as their significant practical implications, little is known about the microdemographic determinants of these paired phenomena. Utilizing methods of asymptotic and stochastic demographic analysis, we reconstruct the microdemographic drivers of this history among one Indigenous population: the Northern Ache of Eastern Paraguay. We then explore the implications of these relationships for understanding the overall …

Mitochondrial Dna Suggests A Western Eurasian Origin For Ancient (Proto-) Bulgarians, D V. Nesheva, S Karachanak-Yankova, M Lari, Y Yordanov, A Galabov, David Caramelli, Draga Toncheva

Human Biology Open Access Pre-Prints

Ancient (proto-) Bulgarians have long been thought to as a Turkic population. However, evidence found in the past three decades show that this is not the case. Until now, this evidence does not include ancient mitochondrial DNA (mtDNA) analysis. In order to fill this void, we have collected human remains from the VIII-X century AD located in three necropolises in Bulgaria: Nojarevo (Silistra region) and Monastery of Mostich (Shumen region), both in Northeast Bulgaria and Tuhovishte (Satovcha region) in Southwest Bulgaria. The phylogenetic analysis of 13 ancient DNA samples (extracted from teeth) identified 12 independent haplotypes, which we further classified …
