Tracing the distribution and evolution of lactase persistence in southern Europe through the study of the T-13910 variant
We investigated the occurrence and intra-allelic variability of the T(-13910) variant located upstream of the lactase gene in 965 individuals from 20 different locations of Italy and Greece. The T(-13910) frequency ranges ...
Analysis of polymorphic sites in the promoter of the nitric oxide synthase 2 gene
A point mutation (G → C) in the gene promoter for the human nitric oxide synthase (NOS) 2 at position -954 is associated with protection against severe Plasmodium falciparum malaria in Gabon. Carriers of this mutation show ...
Brief Communication: mtDNA variation in North Cameroon: Lack of Asian lineages and implications for back migration from Asia to Sub-Saharan Africa
The hypervariable region-1 and four nucleotide positions (10400, 10873, 12308, and 12705) of the coding region of mitochondrial DNA (mtDNA) were analyzed in 441 individuals belonging to eight populations (Daba, Fali, Fulbe, ...
The analysis of variation of mtDNA hypervariable region 1 suggests that Eastern and Western Pygmies diverged before the Bantu expansion
The Eastern Pygmies from Zaire and Western Pygmies from Cameroon, Congo, and the Central African Republic represent the two principal groups of African Pygmies. In the "recent divergence" hypothesis in which Western Pygmies ...
Human microevolution and the atlantic slave trade: A case study from Säo Tomé
Populations derived from the Atlantic slaving process provide unique opportunities for studying key evolutionary determinants of current patterns of human cultural and biological variation. Examination of the genetic ...
Italian isolates today: Geographic and linguistic factors shaping human biodiversity
We briefly review the current status of anthropological and genetic studies of isolated populations and of their micro-evolutionary and biomedical applications, with particular emphasis on European populations. Thereafter, ...
“The Chalcolithic Mummy - in search of immortality”
The origins of dogs: archaeozoology, genetics, and ancient DNA. Domesticazione ed evoluzione dei cani: dati genetici, archeozoologici e ruolo del DNA antico
The domestication of the dog from the wolf was a key step in the pathway that led to the Neolithic revolution. The earliest fossil dogs, dated to the end of the last glacial period (17,000 to 12,000 years ago), have been ...
