Inferring linguistic transmission between generations at the scale of individuals
Historical linguistics strongly benefited from recent methodological advances inspired by phylogenetics. Nevertheless, no available method uses contemporaneous within-population linguistic diversity to reconstruct the history of human populations. Here, we developed an approach inspired from population genetics to perform historical linguistic inferences from linguistic data sampled at the individual scale, within a population. We built four with…
Sahelian pastoralism from the perspective of variants associated with lactase persistence
OBJECTIVES: Archeological evidence shows that first nomadic pastoralists came to the African Sahel from northeastern Sahara, where milking is reported by ~7.5 ka. A second wave of pastoralists arrived with the expansion of Arabic tribes in 7th-14th century CE. All Sahelian pastoralists depend on milk production but genetic diversity underlying their lactase persistence (LP) is poorly understood. MATERIALS AND METHODS: We investigated SNP variants…
The historical spread of A rabian P astoralists to the eastern A frican S ahel evidenced by the lactase persistence −13,915*G allele and mitochondrial DNA
OBJECTIVES: Thanks to the ability to digest lactose, Arabian nomads had become less dependent upon their sedentary neighbors and some of these populations spread to Africa. When and by which route they migrated to their current locations have previously been addressed only by historical and archaeological data. METHODS: To address the question of Arab expansion into Africa, we collected samples from several Arabic populations, especially the Bagg…
Inference of sex‐specific expansion patterns in human populations from Y ‐chromosome polymorphism
Studying the current distribution of genetic diversity in humans has important implications for our understanding of the history of our species. We analyzed a set of linked STR and SNP loci from the paternally inherited Y chromosome to infer the past demography of 55 African and Eurasian populations, using both the parametric and nonparametric coalescent‐based methods implemented in the BEAST application. We inferred expansion events in most sede…
Patrilineal populations show more male transmission of reproductive success than cognatic populations in Central Asia, which reduces their genetic diversity
OBJECTIVE: The extent to which social organization of human societies impacts the patterns of genetic diversity remains an open question. Here, we investigate the transmission of reproductive success in patrilineal and cognatic populations from Central Asia using a coalescent approach. METHODS: We performed a study on the mitochondrial DNA (mtDNA) and Y chromosome polymorphism of patrilineal and cognatic populations from Central Asia. We reconstr…
Post marital residence behaviours shape genetic variation in hunter-gatherer and agricultural populations from Central Africa
The evolution of the sociocultural behaviours determining lineage transmission and post marital residence rules in human societies has been the subject of intense debates in cultural anthropology and ethnology. Population genetics paradigms and methods can provide new insights into the past mobility behaviour of spouse and their influence on the genetic diversity patterns observed today among communities and populations. Here, we review, for a no…
Lactase Persistence in Central Asia: Phenotype, Genotype, and Evolution
The aim of the present study is to document the evolution of the lactase persistence trait in Central Asia, a geographical area that is thought to have been a region of long-term pastoralism. Several ethnic groups co-exist in this area: Indo-Iranian speakers who are traditionally agriculturist (Tajik) and Turkic speakers who used to be nomadic herders (Kazakh, Karakalpak, Kyrgyz, Turkmen). It was recently demonstrated that horse milking practice …

Genetic traces of east‐to‐west human expansion waves in Eurasia
In this study, we describe the landscape of human demographic expansions in Eurasia using a large continental Y chromosome and mitochondrial DNA dataset. Variation at these two uniparentally‐inherited genetic systems retraces expansions that occurred in the past 60 ky, and shows a clear decrease of expansion ages from east to west Eurasia. To investigate the demographic events at the origin of this westward decrease of expansion ages, the estimat…
