Estimating Y chromosome specific microsatellite mutation frequencies using deep rooting pedigrees.
TLDR
Estimates suggest that microsatellites on the Y chromosome have mutation frequencies comparable to those on the autosomes, which supports the hypothesis that slippage-generated growth is the driving force behind the microsatellite variability. Expand
Genomic evidence for the Pleistocene and recent population history of Native Americans
TLDR
The results suggest that there has been gene flow between some Native Americans from both North and South America and groups related to East Asians and Australo-Melanesians, the latter possibly through an East Asian route that might have included ancestors of modern Aleutian Islanders. Expand
Genetic and demographic implications of the Bantu expansion: insights from human paternal lineages.
TLDR
A recent origin for most paternal lineages in west Central African populations most likely resulting from the expansion of Bantu-speaking farmers that erased the more ancient Y-chromosome diversity found in this area, and the intriguing presence of paternal lineage belonging to Eurasian haplogroup R1b1*, which might represent footprints of demographic expansions in central Africa not directly related to the BantU expansion. Expand
Inferring the Demographic History of African Farmers and Pygmy Hunter–Gatherers Using a Multilocus Resequencing Data Set
TLDR
The branching history of Pygmy hunter–gatherers and agricultural populations from Africa and estimated separation times and gene flow between these populations are studied to increase knowledge of the history of the peopling of the African continent in a region lacking archaeological data. Expand
Variation in Rural African Gut Microbiota Is Strongly Correlated with Colonization by Entamoeba and Subsistence
TLDR
It is found that across populations, colonization by this protozoa can be predicted with 79% accuracy based on the composition of an individual's gut microbiota, and several of the taxa most important for distinguishing Entamoeba absence or presence are signature taxa for autoimmune disorders. Expand
Maternal traces of deep common ancestry and asymmetric gene flow between Pygmy hunter–gatherers and Bantu-speaking farmers
TLDR
Analysis of mtDNA variation in 1,404 individuals from 20 farming populations and 9 Pygmy populations from Central Africa revealed that this region was colonized gradually, with an initial L1c-rich ancestral population ultimately giving rise to current-day farmers and Pygmies, in whom L1 c1a is the only surviving clade. Expand
137 ancient human genomes from across the Eurasian steppes
TLDR
The genomes of 137 ancient and 502 modern human genomes illuminate the population history of the Eurasian steppes after the Bronze Age and document the replacement of Indo-European speakers of West Eurasian ancestry by Turkic-speaking groups of East Asian ancestry. Expand
From Social to Genetic Structures in Central Asia
TLDR
It is shown that pastoral populations exhibit a substantial loss of Y chromosome diversity in comparison to farmers but that no such a difference is observed at the mitochondrial-DNA level, indicating that the dynamics of patrilineal descent groups is responsible for these sexually-asymmetric genetic patterns. Expand
Phylogenetic and familial estimates of mitochondrial substitution rates: study of control region mutations in deep-rooting pedigrees.
TLDR
The results reconcile the controversial rate estimates in the phylogenetic and familial studies; the fast sites prevail in the latter, whereas the slow and moderate sites dominate the phylogenetics-rate estimations. Expand
Sex‐specific demographic behaviours that shape human genomic variation
TLDR
It is shown that differences between male and female migration rates matter, but that they are certainly not the only contributing factor, and differences in effective population size between men and women are also likely to account for these differences. Expand
