For societies with writing systems, hereditary leadership is documented as one of the hallmarks of early political complexity and governance. … ⇒
Y-DNA supports population discontinuity between Early Neolithic & Late Neolithic/Early Bronze Age in Cis-Baikal
The study of Ancient DNA (aDNA), DNA recovered from archaeological and historic post mortem material, has complemented the study of anthropology and archaeology. There are several challenges in the retrieval and analysis of DNA from ancient specimens including exogenous contamination with modern DNA, … ⇒
Jonathan S. Friedlaender (2007: 233) on a puzzle of asymmetry — how Polynesians expanding into Remote Oceania ended up with a pre-Austronesian ancestry contribution mediated primarily by Papuan men — and why the same pattern (female-skewed Austronesian input) appears to hold across those Melanesians who now speak Austronesian languages, as well as admixed groups who have remained Papuan speakers:
One proposed explanation is that the ancient Austronesian-speaking populations were “… matriarchal and matrilocal (as the Amis tribe still is in Taiwan) whereby the Y chromosome pool of the initial migrants was lost after being repeatedly diluted on the way toward Polynesia (Trejaut et al., … ⇒

Poor DNA preservation is the most limiting factor in ancient genomic research. In the vast majority of ancient bones and teeth, endogenous DNA molecules only represent a minor fraction of the whole DNA extract, rendering traditional shot-gun sequencing approaches cost-ineffective for whole-genome characterization. … ⇒
Quick remarks (updated 2014.10.23 & 2014.10.27):
(1) Pinhasi makes an impressive case for preferentially targeting the very dense and presumably well-sheltered petrous pyramid of the temporal bone for ancient DNA extraction.
(2) All (four) of the Early and Middle Neolithic males in this study were found to have characteristically hunter-gatherer Y hgs (I2a & C6, which you may remember from Mesolithic La Braña)! Male-biased incorporation of local hunter-gatherers? Very much not what you’d anticipate from the German and Iberian Neolithic series. … ⇒

Widely distributed taxa provide an opportunity to compare biogeographic responses to climatic fluctuations on multiple continents and to investigate speciation. … ⇒
But, besides the Feegeeans, Tongatabooarrs, Erromanggoans, Pannangians, and Brighggians, and, besides the wild specimens of the whaling-craft which unheeded reel about the streets, you will see other sights still more curious. . .

An unexpected finding in a 2010 study (haploid markers only) of a historically Algonquian-speaking Massachusetts Native American population profoundly transformed in collision and fusion with Europeans and West Africans:
Surprisingly, … ⇒
Pardiñas et al. argue in a new article that their recognition of an apparently Iberia-specific sublineage of mtDNA haplogroup L3f in modern Asturians is the legacy of an early Neolithic (if not earlier!) northward crossing of the Strait of Gibraltar. I have my doubts, but it speaks to scenarios that ought to remain under serious consideration.
