Abstract Milk is a major food of global economic importance and its consumption regarded as classic example gene-culture evolution. Humans have exploited animal milk resource for at least 8500 years, but the origins, spread scale dairying remain poorly understood. Indirect lines evidence, such lipid isotopic ratios pottery residues, faunal mortality profiles lactase persistence allele frequencies, provide partial picture this process; however, in order to understand how, where when humans...
The genetic trait of lactase persistence (LP) is associated with at least five independent functional single nucleotide variants in a regulatory region about 14 kb upstream the gene [−13910*T (rs4988235), −13907*G (rs41525747), −13915*G (rs41380347), −14009*G (rs869051967) and −14010*C (rs145946881)]. These alleles have been inferred to spread recently present-day frequencies attributed positive selection for ability adult humans digest lactose without risk symptoms intolerance. One...
The agropastoral communities of Coquimbo, Chile, are characterised by their goat herding-based livelihoods, admixed ancestry, and transhumant mobility. To explore the impact these features on genetic diversity interactions with neighbouring populations. Genotypic polymorphisms 15 STRs were analysed in 466 individuals from communities. Forensic parameters estimated. Genetic structure was assessed using RST, Nei's distances, MDS, dendrograms, STRUCTURE, 23 reference populations South America...
Background: Despite its enormous health and social burden, there are limited published studies describing the epidemiology of violent deaths in Chile. We described mortality rate trends Chile between 2001 2018, current spatial distribution ecological level correlates. Methods: A population-based study using publicly accessible data. calculated age-adjusted rates per 100,000 persons for sex, age, intention, mechanism death. Next, we used linear regression to estimate time sex intention. then...
The genetic trait of lactase persistence is attributable to allelic variants in an enhancer region upstream the gene, LCT. To date, five different functional alleles, −13910*T, −13907*G, −13915*G, −14009*G and −14010*C, have been identified. co-occurrence several these alleles Ethiopian lactose digesters leads a pattern sequence diversity characteristic 'soft selective sweep'. Here we hypothesise that throughout Africa, where multiple co-exist, will be greater groups who are traditional milk...

ABSTRACT Migration research poses several unique challenges and opportunities. Conducting ethical global health practice, especially when studying migrant mental health, is of particular concern. This article explores seven lessons learned in our mixed‐methods study conducted to assess the impact migration experience on Haitian migrants’ Santiago, Chile. The primary were recruiting a highly mobile population, building trust community participation, overcoming language barriers, safety...
Abstract The genetic trait of lactase persistence (LP) evolved as an adaptation to milking pastoralism in the Old World and is a well‐known example positive natural selection humans. However, specific mechanisms conferring this selective advantage are unknown. To understand relationship between milk drinking, LP, growth, reproduction, survival, communities Coquimbo Region Chile, with recent adoption agropastoralism, were used model population. DNA samples data on stature, diet collected from...
Lactase persistence (LP) is a genetic trait that has been studied among different countries and ethnic groups. In Latin America, the frequencies of this have shown to vary according degree admixture populations. The objective study better understand relationship between dairy intake in multiethnic context through synthesis studies conducted four regions Chile.Genotypes for SNP LCT-13910C>T (rs4988235) frequency consumption were obtained from populations: Polynesians Easter Island (Rapanui);...
The notion of a unique turn Western modernity in the ways engagement between politics and life has brought idea political landscape dominated by authoritative discourses promoted an array biological disciplines, techniques technologies. Under such scenario, emergence concept citizenships seems required analytical tool for social sciences. This article poses limitation to reach tools. Based on experiences with mobile goat herders from de Chilean Norte Chico, urban advocates milk-free diets,...
Abstract Background Understanding the sexual and reproductive health practices among university students is crucial due to transitional phase adulthood potential associated risks. This study aimed determine according gender, year, ethnicity. Methods A cross-sectional was conducted between 2018 2021 at University of La Frontera, involving first-year students. The included 5131 participants, accounting for 58.36% total enrolled Among 55.4% were female, average age 18.9 years. Results revealed...
Globally, mortality and fertility rates generally fall as resource abundance increases. This pattern represents an evolutionary paradox insofar resource-rich ecological contexts can support higher numbers of offspring, a component biological fitness. has not been resolved, in part because the relationships between fertility, life history strategies, reproductive behavior, socioeconomic conditions are complex cultural-historically contingent. We aim to understand how we might make sense this...
