La paléogénétique occupe désormais une place importante dans les problématiques archéologiques. Toutefois, les analyses d’ADN ancien peuvent être desservies, voire empêchées, par l’état de préservation des échantillons en raison de contamination par de l’ADN moderne ou de mauvaises conditions de stockage. Le projet beDNA, "banque d’échantillons et de Données Nationale Archéogénétique", souhaite donner les moyens d’analyses paléogénétiques futures…
Is the post-Neolithic Y chromosome bottleneck necessarily explained by violent competition between lineages
Most modern human populations are structured in lineages and/or clans (54%) and display unilineal descent rules, with individuals affiliated to the kinship group of their father (patrilineality, 40%) or of their mother (matrilineality, 14%) only. Moreover, residence rules – defining the place where a couple lives after marriage – such as patrilocality (64%) or matrilocality (20%), involving a differential migration of individuals between populati…

Continuité génétique des populations anciennes et récentes d'Asie Centrale
Depuis la préhistoire, l’Asie centrale méridionale est une région au carrefour des mouvements de populations, de cultures et de marchandises. Aujourd’hui l’Asie Centrale est peuplée par des populations réparties dans deux groupes culturels et linguistiques : le groupe Indo-iranien et le groupe Turco-mongol. L’établissement d’une base de données génétiques sur ces populations a permis d’étudier leur structure génétique en mettant en évidence la mi…

D’année en année, la paléogénétique prend toujours plus de place dans l’étude des populations humaines. Toutefois, les analyses d’ADN ancien peuvent être desservies par la préservation des échantillons, ou la contamination par de l’ADN moderne. L’hétérogénéité des méthodes de conservation des échantillons archéologiques, comme leur dispersion sur tout le territoire national, constituent des freins à ces analyses.

La notion de race. Un regard actuel de la biologie et de la génétique
La systématique est la science qui produit des systèmes permettant d'ordonner la biodiversité et de nommer les catégories ainsi produites. Ces catégories, familles, genres, espèces, races, etc., issues d'un processus de différenciation plus ou moins continu, sont, par nature, floues. Elles rendent compte imparfaitement d'une réalité : l'existence de lignées plus ou moins divergentes. Dans l'espèce humaine, comme dans toutes les autres, des différ…
Ancient human genomes from across the Eurasian steppes
Sex‐specific genetic diversity is shaped by cultural factors in Inner Asian human populations
OBJECTIVES: Sex-specific genetic structures have been previously documented worldwide in humans, even though causal factors have not always clearly been identified. In this study, we investigated the impact of ethnicity, geography and social organization on the sex-specific genetic structure in Inner Asia. Furthermore, we explored the process of ethnogenesis in multiple ethnic groups. METHODS: We sampled DNA in Central and Northern Asia from 39 p…
A Central Asian Language Survey
We have documented language varieties (either Turkic or Indo-European) spoken in 23 test sites by 88 informants belonging to the major ethnic groups of Kyrgyzstan, Tajikistan and Uzbekistan (Karakalpaks, Kazakhs, Kyrgyz, Tajiks, Uzbeks, Yaghnobis). The recorded linguistic material concerns 176 words of the extended Swadesh list and will be made publically available with the publication of this paper. Phonological diversity is measured by the Leve…

Genomic evidence for the Pleistocene and recent population history of Native Americans
Genetic history of Native Americans Several theories have been put forth as to the origin and timing of when Native American ancestors entered the Americas. To clarify this controversy, Raghavan et al. examined the genomic variation among ancient and modern individuals from Asia and the Americas. There is no evidence for multiple waves of entry or recurrent gene flow with Asians in northern populations. The earliest migrations occurred no earlier…
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…
Lactase Persistence Variants in Arabia and in the African Arabs
Lactase persistence (LP), the state enabling the digestion of milk sugar in adulthood, occurs only in some human populations. The convergent and independent origin of this physiological ability in Europe and Africa is linked with animal domestication that either had started in both places independently or had spread from the Near East by acculturation. However, it has recently been shown that at least in its southern parts, the population of Arab…
Genetic Diversity of Four Filipino Negrito Populations from Luzon
Genetic data corresponding to four negrito populations (two Aeta and two Agta; n = 120) from the Luzon region of the Philippines have been analyzed. These data comprise mitochondrial DNA (mtDNA) hypervariable segment 1 haplotypes and haplogroups, Y-chromosome haplogroups and short tandem repeats (STRs), autosomal STRs, and X-chromosome STRs. The genetic diversity and structure of the populations were investigated at a local, regional, and interre…
Short stature in African pygmies is not explained by sexual selection
Interview with Laura Fortunato, Winner of the 2011 Gabriel W. Lasker Prize
Fellow at the Santa Fe Institute in Santa Fe
Dans l’épaisseur du temps
C’est autour de l’année 1859 que la préhistoire s’affirme, à l’échelle de l’Europe, comme un domaine de recherche nouveau et fécond. Les grandes disciplines des sciences naturelles (géologie, paléontologie...) et des sciences de l’homme (archéologie, histoire, philologie...) participent à la création de cette nouvelle science à travers les débats fondateurs portant sur l’ancienneté de l’homme et sur son origine animale. En une décennie, c’est tou…
Indirect evidence for the genetic determination of short stature in African Pygmies
Central African Pygmy populations are known to be the shortest human populations worldwide. Many evolutionary hypotheses have been proposed to explain this short stature: adaptation to food limitations, climate, forest density, or high mortality rates. However, such hypotheses are difficult to test given the lack of long‐term surveys and demographic data. Whether the short stature observed nowadays in African Pygmy populations as compared to thei…
Geographic Patterns of (Genetic, Morphologic, Linguistic) Variation
When sampling locations are known, the association between genetic and geographic distances can be tested by spatial autocorrelation or regression methods. These tests give some clues to the possible shape of the genetic landscape. Nevertheless, correlation analyses fail when attempting to identify where genetic barriers exist, namely, the areas where a given variable shows an abrupt rate of change. To this end, a computational geometry approach …
Y-Chromosome Analysis in Egypt Suggests a Genetic Regional Continuity in Northeastern Africa
The geographic location of Egypt, at the interface between North Africa, the Middle East, and southern Europe, prompted us to investigate the genetic diversity of this population and its relationship with neighboring populations. To assess the extent to which the modern Egyptian population reflects this intermediate geographic position, ten Unique Event Polymorphisms (UEPs), mapping to the nonrecombining portion of the Y chromosome, have been typ…

Lactase Persistence in Central Asia
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…

New method for surname studies of ancient patrilineal population structures, and possible application to improvement of Y‐chromosome sampling
Several studies showed that surnames are good markers to infer patrilineal genetic structures of populations, both on regional and microregional scales. As a case study, the spatial patterns of the 9,929 most common surnames of the Netherlands were analyzed by a clustering method called self‐organizing maps (SOMs). The resulting clusters grouped surnames with a similar geographic distribution and origin. The analysis was shown to be in agreement …
Les probabilités de transmission des gènes fondateurs dans cinq populations régionales du Québec
Certaines maladies héréditaires rares ont une incidence anormalement élevée dans la population québécoise.

One Founder/One Gene Hypothesis in a New Expanding Population
High frequencies of some rare inherited recessive disorders can be found in the Saguenay region of Quebec, Canada. Four disorders have a carrier frequency of about 0.04 (in the range 0.035-0.05): pseudovitamin D-dependent rickets, hereditary tyrosinemia type 1, Charlevoix-Saguenay spastic ataxia, and sensorimotor polyneuropathy with or without agenesis of the corpus callosum. Molecular data suggest that only 1 mutation has been introduced into th…
Senescence of reproduction may explain adaptive menopause in humans
The “mother” hypothesis is one of the main adaptive explanations of human menopause. It postulates that reproductive cessation constitutes a strategy that has been selected for during human evolution because mothers at older ages might maximize their fitness by investing resources in the survival and reproduction of their living children rather than by continuing to reproduce. This study provides a test of this hypothesis. Fertility functions tha…
Genetic consequences of differential demographic behaviour in the Saguenay region, Québec
Some rare inherited disorders are found with a high frequency in the population of the Saguenay region (Québec province, Canada, population 300,000). Inbreeding coefficients are too low to be an explanation for these high frequencies. In the first decades of settlement (1842–1870), most of the immigrants came from a small region called Charlevoix (east of Québec city). As most of the genetic disorders found in the Saguenay region are also found i…

Transmission of migration propensity increases genetic divergence between populations
The advent of molecular genetics has brought invaluable information, which is now routinely used by anthropologists in their attempt to reconstruct our demographic past. Since mitochondrial DNA loci are much more similar between populations than are Y‐chromosome loci, it is suggested that women had a much higher migration rate than men throughout history. Based on an examination of intergenerational migration patterns in three large demographic d…

A Y-chromosome portrait of the population of Jerba (Tunisia) to elucidate its complex demographic history
L’histoire démographique de l’île de Jerba est très ancienne en raison de sa position centrale dans le bassin de la mer Méditerranée, c’est la raison pour laquelle plusieurs populations se sont succédées sur l’île dont la population est, de nos jours, hétérogène (Arabes, Berbères, Noirs, Juifs). Afin d’étudier la variabilité du chromosome Y de la population de Jerba nous avons analysé 10 polymorphismes, SRY-2627 ; SRY-10831a ; SRY-4064 ; 92R7 ; T…

Intervals between marriage and first birth in mothers and daughters
Marriage-first birth intervals are examined in two historical populations, Quebec (1608–1765) and Haut-Jura (1689–1980), comparing intervals in mothers and daughters, and in sister-sister pairs. The results point to a weak relationship between intervals of mothers and daughters, though it does not attain significance. Shared environment does not seem to be responsible since there is no association between pairs of sisters from the same population…
An abnormal concentration of cases of Rendu-Osler disease in the Valserine valley of the French Jura
An important concentration of patients with Rendu-Osler disease occurs in the Valserine valley of the French Jura. A study of marriages shows that, in spite of its somewhat remote location, the valley cannot be considered an isolate, but that, on the contrary, exogamy is widely practised. Only 17.8% of the genes of inhabitants during the present century can be traced to the original population, but persons affected with the disease belong to a su…
Population structure and immigration; a study of the Valserine Valley (French Jura) from the 17th century until the present
The establishment of the genealogies and biographies of inhabitants of selected villages from the Haut-Jura from the 17th century up to the present day has enabled us to demonstrate the major role of immigration on the genetic structure of a population. The evaluation of the effective descendance of native versus immigrant couples shows the imbalance of demographic contribution in favour of the first category. Immigrant couples account for 26% of…

Intergenerational correlation of effective family size in early Québec (Canada)
The use of a comprehensive demographic database of the early French Canadian population (1608–1800) reveals an almost null impact of parents' fertility on children's fertility (r ≃ 0.01–0.05), which contradicts the commonly held view that family size has a tendency to run in families. However, in this population, there is a clear transmission from one generation to the next of the effective family size within a given geographical area (EFS, defin…

Fragmentation of the Qu bec population genetic pool (Canada)
The 6 million French-Canadians of Québec derive from a relatively small number of founders. Consequently, some hereditary diseases, which may or may not present a worldwide distribution, have been detected in high frequency in this population. Several studies, however, indicate a nonuniform distribution of these diseases through the population, suggesting that the French-Canadian founder effect has been geographically stratified. Here we explore …
