- Y-chromosomal evidence of a pastoralist migration through Tanzania to southern AfricaBrenna M Henn
Department of Anthropology, Stanford University, Stanford, CA 94035 2117, USA
Proc Natl Acad Sci U S A 105:10693-8. 2008..Our Y-chromosomal evidence supports a demic diffusion model of pastoralism from eastern to southern Africa approximately 2,000 years ago...
- Characterizing the time dependency of human mitochondrial DNA mutation rate estimatesBrenna M Henn
Department of Anthropology, Stanford University, USA
Mol Biol Evol 26:217-30. 2009..Our findings suggest that human mtDNA estimates of dates of population and phylogenetic events should be adjusted in light of this time dependency of the mutation rate estimates...
- Hunter-gatherer genomic diversity suggests a southern African origin for modern humansBrenna M Henn
Department of Genetics, Stanford University, Stanford, CA 94305, USA
Proc Natl Acad Sci U S A 108:5154-62. 2011..However, African hunter-gatherer populations continue to maintain the highest levels of genetic diversity in the world...
- Limited evidence for classic selective sweeps in African populationsJulie M Granka
Department of Biology, Stanford University, Stanford, California 94305, USA
Genetics 192:1049-64. 2012..Additionally, population history can confound the interpretation of selection statistics, suggesting that greater care is needed in attributing broad genetic patterns to human adaptation...
- Genomic ancestry of North Africans supports back-to-Africa migrationsBrenna M Henn
Department of Genetics, Stanford University, Stanford, CA, USA
PLoS Genet 8:e1002397. 2012..Our genomic data reveal an extraordinarily complex history of migrations, involving at least five ancestral populations, into North Africa...
- African Y chromosome and mtDNA divergence provides insight into the history of click languagesAlec Knight
Department of Anthropological Sciences, Stanford University, Stanford, CA 94305, USA
Curr Biol 13:464-73. 2003..Intriguingly, the language of the Hadzabe of eastern Africa, although not closely related to any other language, shares click consonants and accompaniments with languages of Khwe and San...
- Sequencing Y chromosomes resolves discrepancy in time to common ancestor of males versus femalesG David Poznik
Program in Biomedical Informatics, Stanford University School of Medicine, Stanford, CA, USA
Science 341:562-5. 2013..Our findings suggest that, contrary to previous claims, male lineages do not coalesce significantly more recently than female lineages...
- The genetic prehistory of southern AfricaJoseph K Pickrell
Department of Genetics, Harvard Medical School, Boston, Massachusetts, USA
Nat Commun 3:1143. 2012..In addition, the East African Hadza and Sandawe derive a fraction of their ancestry from admixture with a population related to the Khoisan, supporting the hypothesis of an ancient link between southern and eastern Africa...

Department of Genetics, Stanford University, Mail Stop 5120, Stanford, California 94305
Hum Biol 84:641-94. 2012..However, we also present evidence that this region is the target of selection in the form of positive selection on the α- and β-haplotypes and of purifying the selection against α/β recombinants. ..
