Y chromosome sequence variation and the history of human populations
Binary polymorphisms associated with the non-recombining region of the human Y chromosome (NRY) preserve the paternal genetic legacy of our species that has persisted to the present, permitting…
The phylogeography of Y chromosome binary haplotypes and the origins of modern human populations
A set of unique event polymorphisms associated with the non‐recombining portion of the Y‐chromosome (NRY) addresses this issue by providing evidence concerning successful migrations originating from Africa, which can be interpreted as subsequent colonizations, differentiations and migrations overlaid upon previous population ranges.
Origin, diffusion, and differentiation of Y-chromosome haplogroups E and J: inferences on the neolithization of Europe and later migratory events in the Mediterranean area.
The phylogeography of Y-chromosome haplogroups E and J was investigated in >2400 subjects from 29 populations, mainly from Europe and the Mediterranean area but also from Africa and Asia, revealing spatial patterns that are consistent with a Levantine/Anatolian dispersal route to southeastern Europe.
Excavating Y-chromosome haplotype strata in Anatolia
This comprehensive characterization of Y-chromosome heritage addresses many multifaceted aspects of Anatolian prehistory, including: the most frequent haplogroup, J, splits into two sub-clades, one of which (J2) shows decreasing variances with increasing latitude, compatible with a northward expansion.
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.
The Role of Selection in the Evolution of Human Mitochondrial Genomes
The surplus of nonsynonymous mutations is a general feature of the young branches of the phylogenetic tree, affecting also those that are found only in Africa, and a new calibration method is introduced to estimate the coalescent times of mtDNA haplogroups.

It is estimated that the spread of Y chromosomes out of Africa is much more recent than previously was thought, and the data indicate substantial population growth in the effective number of human Y chromosomes.

The analysis reveals no evidence for any archaic maternal or paternal lineages in Australians, despite some suggestively robust features in the Australian fossil record, thus weakening the argument for continuity with any earlier Homo erectus populations in Southeast Asia.
Origins and divergence of the Roma (gypsies).
Principal-components analysis and analysis of molecular variance indicate that genetic structure in extant endogamous Romani populations has been shaped by genetic drift and differential admixture and correlates with the migrational history of the Roma in Europe.
Phylogeography of Y-chromosome haplogroup I reveals distinct domains of prehistoric gene flow in europe.
Haplogroup I, the only major clade of the Y phylogeny that is widespread over Europe but virtually absent elsewhere, is analyzed, in detail, and it is revealed that it underwent a postglacial expansion and marked the human colonization of Sardinia approximately 9,000 years ago.
