A back migration from Asia to sub-Saharan Africa is supported by high-resolution analysis of human Y-chromosome haplotypes.
Phylogeographic analyses suggest that a large component of the present Khoisan gene pool is eastern African in origin and that Asia was the source of a back migration to sub-Saharan Africa.
Variation of female and male lineages in sub-Saharan populations: the importance of sociocultural factors.
The role of polyginy and patrilocality is sustained by the evidence of a differential pressure of genetic drift and gene flow on maternal and paternal lineages of food producers and hunter-gatherers that is revealed through the analysis of mitochondrial and Y-chromosomal intrapopulational variation.

Analysis of frequency patterns and diversity in the largest collection of R-M269-related chromosomes yet assembled reveals no geographical trends in diversity, in contradiction to expectation under the Neolithic hypothesis, and suggests an alternative explanation for the apparent cline in diversity recently described.
Brief communication: mtDNA variation in North Cameroon: lack of Asian lineages and implications for back migration from Asia to sub-Saharan Africa.

It is suggested that modern populations of North Cameroon originated from a small population group which migrated from Asia to Africa and in which, through genetic drift, Y-chromosome haplotype R1*-M173 became predominant, whereas the Asian mtDNA haplogroups were lost.
The Analysis of Variation of mtDNA Hypervariable Region 1 Suggests That Eastern and Western Pygmies Diverged before the Bantu Expansion
The variation of the hypervariable region 1 of the mitochondrial DNA in the Mbenzele, Western Pygmies of the Central African Republic, and compared with those of previous mtDNA and Y chromosome studies was found to be congruent with the pre‐Bantu divergence but failed to support the recent divergence hypothesis.
Mitochondrial DNA from prehistoric canids highlights relationships between dogs and South-East European wolves.

A-DNA support for the involvement of European wolves in the origins of the three major dog clades is provided and genetic data suggest multiple independent domestication events.
Phylogeography of the human mitochondrial L1c haplogroup: genetic signatures of the prehistory of Central Africa.
The 5300-year-old Helicobacter pylori genome of the Iceman
The “Iceman” H. pylori is a nearly pure representative of the bacterial population of Asian origin that existed in Europe before hybridization, suggesting that the African population arrived in Europe within the past few thousand years.
A Study of Y-Chromosome Microsatellite Variation in Sub-Saharan Africa: A Comparison between F ST and R ST Genetic Distances
It is suggested that Y-chromosome microsatellite data may provide useful information for analyses of interpopulational diversity among sub-Saharan populations if an adequate number of loci and individuals along with an appropriate genetic distance method are used.
Phylogeographic Refinement and Large Scale Genotyping of Human Y Chromosome Haplogroup E Provide New Insights into the Dispersal of Early Pastoralists in the African Continent
Time frames, phylogenetic structuring, and sociogeographic distribution of E-V1515 and its subclades are consistent with a multistep demic spread of pastoralism within north-eastern Africa and its subsequent diffusion to subequatorial areas.
