Another look at mtDNA
The new article in The American Journal of Human Genetics, A “Copernican” Reassessment of the Human Mitochondrial DNA Tree from its Root, is open access, so you should check it out. The discussion gets to the heart of the matter:
Supported by a con…
Out of Africa and out of Siberia
The latest edition of The American Journal of Human Genetics has two papers using “old fashioned” uniparental markers to trace human migration out of Africa and Siberia respectively. I say old fashioned because the peak novelty of these techniques was around 10 years ago, before dense autosomal SNP marker analyses, let alone whole genome sequencing. […]
“What if you’re wrong” – haplogroup J
Back when this sort of thing was cutting edge mtDNA haplogroup J was a pretty big deal. This was the haplogroup often associated with the demic diffusion of Middle Eastern farmers into Europe. This was the “Jasmine” clade in Seven Daughters…
Man at Bab el-Mandeb
In light of my last post I had to take note when Dienekes today pointed to this new paper in the American Journal of Physical Anthropology, Population history of the Red Sea—genetic exchanges between the Arabian Peninsula and East Africa signaled i…
Neandertal hybridization & Haldane’s rule
Mr. James Winters at A Replicated Typo pointed me to a short hypothesis paper, Neanderthal-human Hybrids. This paper argues that selective mating of Neandertal males with females of human populations which had left Africa more recently, combined with
Icelanders descended from Native Americans?
That is the question, and tentatively answered in the affirmative according to a new paper in The American Journal of Physical Anthropology. A new subclade of mtDNA haplogroup C1 found in icelanders: Evidence of pre-columbian contact?:
Although most mtDNA lineages observed in contemporary Icelanders can be traced to neighboring populations in the British Isles and Scandinavia, […]
