An Aboriginal Australian Genome Reveals Separate Human Dispersals into Asia
It is shown that Aboriginal Australians are descendants of an early human dispersal into eastern Asia, possibly 62,000 to 75,000 years ago, which is separate from the one that gave rise to modern Asians 25, thousands of years ago.
Genomic evidence for the Pleistocene and recent population history of Native Americans
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.
Ancient DNA reveals male diffusion through the Neolithic Mediterranean route
The Y-haplotype lineages characterized and the study of their current repartition in European populations confirm a greater influence of the Mediterranean than the Central European route in the peopling of southern Europe during the Neolithic transition.
A recent bottleneck of Y chromosome diversity coincides with a global change in culture.
A study of 456 geographically diverse high-coverage Y chromosome sequences, including 299 newly reported samples, infer a second strong bottleneck in Y-chromosome lineages dating to the last 10 ky, and hypothesize that this bottleneck is caused by cultural changes affecting variance of reproductive success among males.
A genomic history of Aboriginal Australia
A population expansion in northeast Australia during the Holocene epoch associated with limited gene flow from this region to the rest of Australia, consistent with the spread of the Pama–Nyungan languages is inferred.
Genomic analyses inform on migration events during the peopling of Eurasia
A genetic signature in present-day Papuans that suggests that at least 2% of their genome originates from an early and largely extinct expansion of anatomically modern humans (AMHs) out of Africa earlier than 75,000 years ago is found.

DNA extracted from human remains excavated in a Spanish funeral cave is studied to obtain information on the early Neolithic funeral practices and on the biogeographical origin of the inhumed individuals, indicating a surprising temporal genetic homogeneity in these groups.

Broad geographical screening of Malagasy and Indonesian genetic variation is reported, from which a statistically robust coalescent model of the island's initial settlement is inferred, raising the possibility that Madagascar was settled not as a large-scale planned colonization event from Indonesia, but rather through a small, perhaps even unintended, transoceanic crossing.
Complete mitochondrial DNA sequences provide new insights into the Polynesian motif and the peopling of Madagascar
Complete mtDNA genome sequencing reveals a new variant of the Polynesian motif in Madagascar, and this newly defined ‘Malagasy motif’ occurs at high frequency in all three ethnic groups, and its phylogenetic position, geographic distribution, and estimated age all support a recent origin, but without conclusively identifying a specific source region.
