Historical admixture results

I am running historical admixtures using Globetrotter software.  The results will be added to this same blog entry.

Western Volga-Finnic (mainly Mordvas)

time:  36 generations, near 1000 years ago

East_Slavic    0,4867536482
Baltic    0,2887079451
Central_European    0,0570663623
Mongola    0,051551692
East_Volga_Finnic_Chuvash    0,04939485
Mansi_Khanty    0,0270296952
East_Baltic_Finnic    0,0169141037
South_European    0,0098787291
Central_Siberian    0,0073332031
North_Siberian    0,0023436624
North_Baltic-Finnic_G4    0,0015424098
Saami    0,0014836991

East_Volga_Finnic_Chuvash stands for Maris, Chuvashes and Udmurts, East Baltic Finns for Karelians and Vepsians, North Finnic G4 for Ingrians.


West_European    0,6080567694
Baltic    0,203714483
North_Baltic_Finnic_G3    0,092400554
North_Baltic_Finnic_G1    0,0431817267
East_Slavic    0,0387924755
Saami    0,0096464481
North_Siberian    0,0042075434

Globetrotter was not able to infer the admixture date.  Groups North_Baltic_Finnic_G1 and North_Baltic_Finnic_G3 are both Finnish. I modified references from the previous blog entry.  Now the South_Baltic_Finnic is split into Baltic and Finnish portions.


time: 56 generations, around 1500 years ago

East_Baltic_Finnic    0,2279573629
North_Baltic_Finnic_G1    0,1883732327
North_Baltic_Finnic_G3    0,134836117
Basque    0,1242665217
North_Siberian    0,1043483876
West_European    0,0686019039
Central_Siberian    0,0590794466
North_Baltic-Finnic_G4    0,0513959273
Baltic    0,0303972753
East_Volga_Finnic_Chuvash    0,0107438251

Groups North_Baltic_Finnic_G1 and North_Baltic_Finnic_G3 are Finnish, North_Baltic_Finnic_G4 is Ingrian and East_Baltic_Finnic is Karelian+Vepsian.  Basque ancestry was higher that among modern Saamis.

 update 30.11.17

After separating Estonians from the main Baltic group it is possible to test also Estonians.  At first however Finnish results,  Estonians still with Balts.

North Baltic-Finnic, group 1

time: 70,6 generations, near 2000 years ago

Baltic    0,7403595543
Saami    0,1586845132
Mansi_Khanty    0,0874546485
North_Siberian    0,0117447072
Central_Siberian    0,0017565769

Basically this was expected,  the Baltic part (including Estonians) is highest and the rest is composed from Euro-Siberian populations.  What surprises is the Mansi-Khanty part, I would have expected  even more Saami or some Mari-Chuvash -like minor admixture.   However the magnitude is right; three quarters Baltic plus one quarter mixed Euro-Siberians.   2000 years sounds credible, it is near the time of the migration of Baltic Finns to Finland.

North Baltic-Finnic, group 2

time: 43,8 generations,  around 1200 years ago

Baltic    0,6802833838
Scandinavian    0,1470929006
Saami    0,1149188786
Mansi_Khanty    0,0503062607
Central_Siberian    0,0038576149
North_Siberian    0,0035409614

Scandinavian admixture appears around 1200 years ago.  It is impossible to name any exact Scandinavian migration or demographic event in Finland, but the first Swedish crusade can be ruled out.  Scandinavian increases, Baltic and Euro-Siberian decreases.

North Baltic-Finnic, group 3

time: 69 generations, around 1900 years ago

Baltic    0,7973987698
Saami    0,1346869263
Mansi_Khanty    0,0644377493
North_Siberian    0,0032512571
Central_Siberian    0,0002252975

The group 3 is very similar to the group 1, both are Finnish, as well as the group 2.

North Baltic-Finnic, group 4 (Ingrians)

time: 106 generations, around 2900 years ago

Baltic    0,7901064987
Saami    0,1221914423
North_Siberian    0,0845129477
Central_Siberian    0,0031891113

Surprisingly this doesn't look like an East-Finnish migration, which was expected.  It reminds me of an extinct Baltic-Finnic population.

Eastern Baltic-Finnic (Karelians and Vepsians)

time: 43,2 generations, near 1200 years ago

Baltic    0,8118374791
Saami    0,099396225
East_Volga_Finnic_Chuvash    0,0295501283
Mansi_Khanty    0,0263499058
Central_Siberian    0,0214967778
North_Siberian    0,0113694841

Near 1200 years match with the formation of East Baltic-Finnic people.

Estonians with Finnish references

time unclear
