Focusing on ancient population genomics research search this blog Tuesday, October 21, Ancient genomes from the Great Hungarian Plain This open access paper on the genetic prehistory of the Great Hungarian Plain is full of surprises. Here are a few of my observations: But what’s happened to the C6 since then? Indeed, they clearly show a northern influence relative to all of the Neolithic farmers and the Iron Age IR1. However, it also shows significant Northern European-like ancestry, and is even inferred to have fair hair, which makes me think that its eastern shift might be in large part due to Eastern Hunter-Gatherer EHG or Yamnaya-related admixture, which is now pervasive across Northern Europe see here. And yet, it’s again missing from the line-up.

You are leaving the Ancestry website. People in this DNA ethnicity group may identify as: Geographically dominated by France in the west and Germany in the east, it includes several nations with distinct cultural identities.
But, when looking at the map, I noticed that “Northwestern Europe” significantly overlaps with western Germany. Perhaps my dad’s family originally came from that part of Germany, but that DNA now registers as part of the England group.
Demic versus cultural diffusion. In the red regions, the Neolithic spread was slow and due to cultural diffusion. In the yellow regions, the spread was faster and dominated by demic diffusion. In the blue regions, the speed was still faster and either demic or cultural diffusion could have dominated this conclusion is due to parameter uncertainty. Note that some regions contain none or just a few sites and are thus highly uncertain, e. Purely demic model Several purely demic models have been proposed.
The simplest one is given by Fisher’s equation [ 8 ] 2. Logistic growth functions are well known to agree with many population data for humans see citations in [ 10 ].

Apr 10, · My DNA estimates I am 64% Great Britain, 14% Europe West, 9% Scandinavian, 8% Ireland, 4% trace areas, and 1% West Asian. In regards to my ancestors of Europe West, they all came from Badden, Germany and surrounding areas.
I2a1b which may well be all them is currently found often in large frequencies in the Balcans and Eastern Europe with some presence also in the eastern areas of Central Europe. I2a1 probably I2a1a but not tested for the relevant SNPs was also found, together with G2a, in a Chalcolithic population of the Treilles group Languedoc and seems to be somehow associated to Cardium Pottery Neolithic.
Autosomal DNA and derived speculations Most of the study incl. To begin with, they generated a PCA plot of West Eurasians with way too many pointless Bedouins and Jews, it must be said and projected the ancient Europeans, as well as a whole bunch of Circum-Pacific peoples on it: The result is a bit weird because, as you can see, the East Asians, Native Americans and Melanesians appear to fall way too close to the peoples of the Caucasus and Anatolia. This seems to be a distorting effect of the “projection” method, which forces the projected samples to align relative to a set of already defined parameters, in this case the West Eurasian modern PCA.
So the projection basically formulates the question: And then answers it as follows: Similarly, it is possible but uncertain that the ancient European and Siberian sequences show some of this kind of distortion. However I have found experimentally that the PCA’s dimension 1 but not the dimension 2, which corresponds largely to the Asian-specific distinctions still correlates quite well with the results of other formal tests that the authors develop in the study and is therefore a valuable tool for visualization.
By the moment the PCA is asking and answering three or four questions by projecting ancient European and Siberian samples in the West Eurasian plot: If ancient Siberians are forced to be defined in modern WEA terms, what would they be?
Britons still live in Anglo
That makes for a lot of folks doing German genealogy research. I spend a good portion of each work day dealing with German ancestry issues — either my own; or as a publisher of German research guides, those of others. I got to thinking that maybe I should compile a detailed listing of the many resources found free of charge at the FamilySearch. Following is a somewhat annotated list that I hope you will find useful. The information is linked, with informational data about the databases from the website, as well as some of my own observations.
The FamilySearch Historical Databases for Germany — as of today, includes 56 collections, twelve of them indexed.
My DNA results gave me 46% Europe West, and only 2% British! I understand the diversity of the Britons, but that result would mean that my mom is over 90% Europe West, when the average percentage of a Briton would be much lower- I believe in the 30% range.
Messenger The European shale gas boom has not materialised in the way that some were predicting. We are a far cry from the situation a few years ago, where interest in fracking in Europe was gathering pace on the back of the successes in North America. The UK appeared to be leading the way, with drilling activities in north-west and south-east England.
Companies started snapping up exploration licences right across the continent, and prospects from Scandinavia to the Urals found themselves being eagerly appraised. Western Europe Of the countries in mainland western Europe, France has the most potential for unconventional hydrocarbons. The shales of the Paris Basin are thought to have major shale gas and minor shale oil potential, while the Jurassic shales in the south-east of the country may also have some shale gas potential.
But a fracking moratorium has been in place since , and was upheld in
Eurogenes Blog: First genome of an Upper Paleolithic human
Researchers analyzed the genomes of Ashkenazi Jews and compared them to those of non-Jewish Europeans in order to determine which genetic markers are unique to Ashkenazi Jews. Such thorough genetic cataloging could help clinicians interpret individual genetic mutations, improve disease mapping and provide insight into the histories of Middle Eastern and European populations, the study said. The findings are also expected to help with disease research in other ethnic groups.
We see this study serving as a vehicle for personalized medicine and a model for researchers working with other populations.
^The reason for the Y-DNA gap between modern Germany and Poland is the resettlement of a whole segment of population that made up part of the west/east gradient along the North European plain.
Genetic genealogy on the other hand combines DNA testing with genealogical and historical records, and typically makes use of large databases to identify matches, or direct comparisons to test for expected matches. There is some overlap between the two, but genetic genealogy is generally more reliable because of its use of additional information: There are three main types of genetic ancestry test: Only males carry a Y-chromosome, but a female can learn about her father line, for example, through her father or brother.
Among the tests currently available there is much variety in the amount of information provided. The markers tested are of two types: These markers have different mutation rates and so give information at different time depths. The information you receive depends on which and how many markers of each type are tested.

So suggests new research that tracked changes in two genes thought to help regulate brain growth, changes that appeared well after the rise of modern humans , years ago. That the defining feature of humans — our large brains — continued to evolve as recently as 5, years ago, and may be doing so today, promises to surprise the average person, if not biologists. Lahn and colleagues examined two genes, named microcephalin and ASPM, that are connected to brain size. If those genes don’t work, babies are born with severely small brains, called microcephaly.
Using DNA samples from ethnically diverse populations, they identified a collection of variations in each gene that occurred with unusually high frequency.
The map above shows what the borders of Europe, the Middle East and North Africa might look like if they were based on the dominant Y-DNA haplogroup rather than .
As you might have concluded by now, if you have Europe South ethnicity in your DNA results, there is a good chance that you have ancestors from the region. Generally speaking, the higher percentage of Europe South DNA ethnicity that shows up in your results, the higher the probability is that the result is correct. Additionally — also generally speaking — the higher the percentage of Europe South DNA ethnicity that you have, the more recent the ancestor is who you inherited this ethnicity from.
Keep this in mind when trying to determine how far back on your family tree you need to look to find your Europe South ancestor. Some of you might have more recent Europe South ancestors. There are 17 total regions that contain these profiles, and they are broken down into these four categories: This can be an indicator of relatively recent Europe South ancestry, though you will still have to do more traditional family tree research to determine where your recent ancestors were born, and where their parents and grandparents came from.
One of the most reliable ways to determine if your Europe South ancestry is recent is to check carefully through your DNA matches. If you have parents, grandparents, or great-grandparents who were born in the Europe South region, you should have DNA matches who either live there now, or have recent ancestors from the region, as well.
Interbreeding With Neanderthals
The interactions probably happened across the area inhabited by Neanderthals. And today, in his office overlooking Avenue Louis Pasteur in Boston, he picks up a blue marker, walks up to a blank white wall, and shows the result to me. He starts with a pair of lines—one for humans and one for Neanderthals—that split off from a common ancestor no more than , years ago. The human branch divides into lineages of Africans, Asians, and Europeans, and then into twigs for smaller groups like the people of New Guinea or the residents of the remote Andaman Islands in the Indian Ocean.
Reich also creates a branch off the Neanderthal line for the Denisovans, a paleolithic lineage geneticists discovered only a few years ago. All well and good.

The absolute dates refer to the whole dissemination areas of the cultures [ 2 , 3 , 5 , 7 , 9 ]. Online version in colour. Traditionally, scholars have explained the Neolithic transition either as an expansion of early farmers from the Near East, who brought new ideas as well as new genes demic diffusion [ 14 — 17 ], or as an adoption of farming technologies by indigenous hunter—gatherer populations with little or no genetic influence cultural diffusion [ 18 — 21 ].
These two contrasting models have been merged into complex integrationist approaches, considering small-scale population movements on regional levels [ 1 , 2 , 10 , 22 ]. Inferences drawn from present-day genetic data have yielded contradictory results about the Neolithic impact on the genetic diversity of modern Europeans, showing a disparity between mitochondrial DNA mtDNA and Y chromosomal patterns. Several Y chromosome studies supported the Neolithic demic diffusion model [ 17 , 23 , 24 ], while most mtDNA and some Y chromosomal studies have proposed a continuity of Upper Palaeolithic lineages [ 20 , 21 , 25 , 26 ].
AncestryDNA Review & Rating
If you have German or Austrian grandparents, for example, you might have been expecting to find German or Austria as an ethnicity percentage. There are two main reasons for this: Ancestry DNA is currently working on an update that will provide more specific regions for those of us with Western Europe ancestry, but there is no official word as to when the update will be ready.
Some people have found their results have been updated as part of a beta test for the new and improved ethnicity results. I personally am very excited about being able to break down some of these broad European categories, like Europe West, into more specific regions.

Haplogroup or haplogroup is a human Y-chromosome DNA haplogroup which is distributed in a large region in Eurasia, extending from Scandinavia and Central Europe to southern Siberia and South.
The 6-foot-9, pound Johnson has no doubt it was Bigfoot, or Sasquatch, the at-least foot-tall, primate-like, hairy creature legendary in the Pacific Northwest and considered a myth by most. The Grants Pass psychologist told his tale on television and in the papers across the country, even internationally. He created the Southern Oregon Bigfoot Society so people could join together to chase the beast.
Johnson still gets emotional talking about his encounter. He is also part owner of Kentucky Bigfoot, along with Charlie Raymond. Com has published an article he wrote about a Cherokee man he visited while researching his book, in Bigfoot and the Cherokee Hill. The article was previously published at Kentucky Bigfoot Sightings Reports along with lots of pictures.
