European IBD statistics

 Many online genetic services provide individual  ancestry results but don't reveal their methods.  For me 9 of 10 services give Finnish plus minor 5-8% admixture of Greek or Italian.  I have seen a man of fully Croat ancestry getting additionally 12 % Orcadian ancestry.  Surprising Orcadian in Balkans, really? Only to mention two examples. Those ancestry testing companies looks like modern alchemists.  My advice is, don't pay, you can get ancestry tests for free from services using open source softwares.   Maybe results of open source softwares are not perfect, but at least you have a possibility to find out how the results are done. 

It is obvious that these companies use a special data adaptation and model putative ancestral pools to geographical locations according their own approaches, but they are not professional historians.  Maybe there is seen a growing genealogical demand in countries where the paper trail is incomplete or they simply try to give a shortcut bypassing paper trail, but according my experience there is no substitute for the old fashion genealogy work.  I am not going to start searching my Italian cousins, because  my paper trail, fully covering to the end of the 17th century, doesn't show Italian roots.

A new Finnish study about yDna haplogroups

 A new study observes yDna haplogroup frequencies and CAD (Coronary artery disease), in Finnish sepelvaltimotauti) vulnerability of haplogoups in Finland.  Haplogroup frequencies show very close same number with the study Lappalainen et al. 2006, but differ from the study Neuvonen et al. 2015.  New haplogroup proportions are


N1c1 60,18 %
I1 26,44 %
R1a1 5,99 %
R1b 5,01 %
I2 0,97 %
E1b1 0,51 %

The study is dowloadable from the link in the end of the following textlink

Results figuring CAD are contradictory with another Finnish study.  This study (published in a Finnish medical magazin Duodecim by Joel Nuotio*, Tomi T. Laitinen* ja Markus Juonala, Link) gives following results, showing the highest vulnerability of CAD in East Finnish regions where the proportion of N1c1 is highest and the lowest vulnerability was found in Southwest regions where the N1c1 proportion is the second highest.  

Picture:









A - autosomal genetic structure in Finland

B - CAD incidence

C - genomewide CAD risk


I see two main factors involved with the disease vulnerability

- way of life

- autosomal inheritance


The Duodecim article shows the highest CAD incidence in the northeast and lowest in the southwest, both areas having the highest N1c1 proportions in Finland.  The way of life is today quite the same everywhere in Finland, thanks to the similar food markets and consistent culture  in the whole  country.  So what remains is differences in the autosomal inheritance.  Southwest and east have been isolated from each other hundreds years in the Finnish history and we can predict also significant difference in the autosomal inheritance of those two areas, the difference we can also see using autosomal genome tests.  Basically the areas of the HG I1 are between southwestern and eastern N1c1 areas and we can predict that the CAD vulnerability of I1 should be between the vulnerability of those two N1c1 areas.

Patterns of genetic connectedness between modern and medieval Estonians and Finns

 A new Estonian study sets the connection between our countries to the 8th and 10th centuries AD and bases it on an assumed Estonian migration to Finland.  Sounds like Estonian self-seeking idea about  Estonian Vikings.  Heard before.  I have not knowledge about such Estonian migration.

  There have been a lot connections between our countries, but historians have never mentioned exactly aforementioned time frame as a significant event in our history.  Sure people have moved from Estonia to Finland, but also conversely.  Historians suggest that the main migration bringing the Baltic Finnic language happened during the Roman Iron Age and we know for sure that around 20-30% of the North Estonian population had Finnish origin after the Swedish era in the 17th century.  We know it because we have original documents.  Those times were very exhausting in Estonia due to many wars and the Estonian population size decreased remarkably.  

Such a Late Iron Age migration from Estonia should also be seen by an elevated R1a proportion in Finland, but the small R1a amount in Finland doesn't imply any Estonian origin.  I stay waiting for wider scientific stance.

The grave of Viking female revealed many surprises

 It was long assumed that the grave was made for a woman, for a Viking queen or princess. Archaeological evidences spoke about a female, clothes and jewellery were typical for a female, but the luxurious sword gave a hint about a male.  The sword was so fine and luxurious that it has been a model for replicas sold under the topic "Sword of Suontaka Viking princess".  But genetic analyses  revealed that the buried one was not a typical man or woman, the remains showed signs of both, namely a chromosomal XXY structure.

The dichotomy between Eurasian and African X chromosomal haplotypes

I made a statistics showing a full bifurcation between East-Asia and Africa. Showing high similarity in the whole Eurasia it is likely that the Eurasian haplotype is related to the OOA event. To see how much the African haplotype in Europe represents Near East migrations needs more investigation. The result implies however that not all and there have been different evolution and migration routes in Eurasia. The haplotype includes 15 SNPs.

Lost Finnish study

 I found newly some information about once lost Finnish study on the Eupedia forum, but still the source unknown.  If you know where is this data from, please inform me, I appreciate it.  I assume that the study can be published during this autumn, but can't be sure.   I suppose it has been on the agenda of the deleted symposium EAA2020.


This is interesting especially because of the certain illogicality between released yDna and autosomal data.

Abstract format: Poster

Southwest Finland has rich Late Iron Age archaeological records that show diverse cultural and trade networks. Ancient DNA analyses
from human remains, however, have remained scarce due to the acidic Finnish soil that leads to a rapid decay of bone material.
Two large inhumation burial grounds from the Crusade Period (1050–1150 CE) in Southwest Finland, Raisio Kansakoulunmäki and
Masku Humikkala, represent the transition period towards Christianity. The favourable skeletal preservation on these sites offers a
possibility to analyse the genetic structure of the Iron Age communities behind the burial context. Combining this genetic data to
other periodically and regionally close individuals enables an in-depth examination of the population history of Late Iron Age Southwest Finland.
In this archaeogenetic study we investigate the genetic composition of altogether 29 individuals, 14 from Kansakoulunmäki and
15 from Humikkala. A closer analysis of kinship patterns and genetic ancestry provides comprehensive information of the Late
Iron Age communities, such as family relations and patrilocality. All samples in this study have been processed in dedicated cleanroom facilities.
Ancient DNA libraries have been enriched for ancestry-informative markers in human DNA, and the data retrieved
with high-throughput next-generation sequencing. The preliminary results for seven Raisio Kansakoulunmäki individuals indicate a
genetic continuity with contemporary Finnish populations. Our current analyses intend to provide a detailed view of the ancestry
components, kinship and genetic affinities for all successful samples.

Are East Finns really eastern conquerors. Fiction and truth.

 Being active in the internet I often meet these ideas.  Russians often have opinion about eastern conquerors that populated Finland.  Westerners have another weird habit; they dig again and again 80 - 150 years old dusty papers to prove something.  We have in Finland our own stories, sometimes supported by our researchers, unfortunately.  Common for those people is denialism, they don't want to use up-to-date and comparable scientific  results and if they use available new data they will always find a loophole how to support those 80-150 years old dusty papers.  One of those ideas is to prove that the Finns came from the far east and so East Finnish people have to be an evidence because they are the most eastern Finnish group..


I made a series of Dstat-statistics to see where the East Finns locate on the east-west axis.  I have genealogically proven samples from all Finnish regions and also  classified samples from the 1000 genomes project. 

 

East Finns are closer Southwest Finns than they are from Karelians, despite of the historical Swedish connection of Southwestern Finns.

I made more comparisons to see a bigger view and I can cast a challenge.  If someone can give any non-Finnish sample group being closer East Finns than East Finns are from Southwest Finns, I will publish the results and give all kudos to her/him.  Only group on the Russian side I rule out is Ingrians who actually are East Finns who migrated to Russia during the historic era.

FIN-Southwest-proved is from the seaside of Finland Proper and consists of 5 samples.
