Genetic Ancestry

Got myself a weird and wacky birthday present for myself this year.. a DNA report showing my Genetic Ancestry.

Like most Aussies our ancestry has been filtered out over generations and most of us arn't that sure where our family comes from. My Nan told me I had a great great grandfather who came from Szczecin Poland which matches up with the results being the highest score for closest genetic relatives today (Northwest Poland) and also the highest score for deep ancestral origins (Northwest Poland), which probably indicates my ancestry was in the region for hundreds of years before my great great grandfather migrated.

My siblings and I have also suspected that we had some Aboriginal (hidden) somewhere in our family for several reasons, the main one being some of my Dad's side of the family in Gloucester look Aboriginal. I was hoping the test would give a more conclusive answer to this question, it does show we are in the 70's% match to European-Aboriginal (mixed) in the 'Extended match results' so I think this gives some evidence to our theory.

This might also explain my general obsession with Europe/Scandinavia area and wanting to go there.

I have no idea how Brazil comes into the picture.

I was wondering what the small dot on Africa could mean (in the world region map below), perhaps linked to the mixed Aboriginal ancestry or does it show where all humans have come from thousands of years ago.

Results below:

^Native Population Match Results - Deep Ancestral Origins:

These results are your Top 20 matches in a database of 846
native populations that have experienced minimal movement and admixture in modern history (approximately, the last 500 years).

Individual matches do not necessarily indicate recent social or cultural affiliation with a particular ethnicity. Instead, your Native Population Match results identify populations where your DNA is most common, reflecting your deep ancestral origins.


^Global Population Match Results - Closest genetic relatives today:

These results are your Top 20 matches in a database of 1,134 global populations, including native peoples as well as Diaspora groups that expanded from their homelands and sometimes admixed with other populations in recent history.

The geographical distribution of your Global Population Match results indicates your closest genetic relatives today and peoples whose blend of geographical ancestry is most similar to your own.

^World Region Match - General view over hundreds or thousands of years:

World Region Match represents the most comprehensive portion of your genetic ancestry analysis. These regions are the product of long term patterns of interactions between peoples within major geographic and cultural zones over hundreds and often thousands of years. World region results provide a broader, more general view of where your genetic ancestry is found among major regions of the world.

The highest score indicates your primary geographical affiliation, and subsequent scores indicate secondary regions where your blend of ancestry is present and/or possible sources of admixture.
The regions where your DNA profile is most frequent are mapped as large circles, and other regions are plotted as circles visually scaled according to match scores.

The Finnic region is the northernmost region of Europe and home to Finns, Estonians and related Scandinavian peoples. These northern cultures are distinguished by their Uralic languages, related to tongues spoken in Hungary and by some ethnic groups of Western Siberia.

^Europa Report:

A specialized analysis that includes a detailed comparison to genetic sub-regions of Europe. The scorescan be compared to more general world region match score information in the 'World Region Match' map.

This map identifies the sub-regions of Europe where your DNA profile is most common. These genetic sub-regions include both geographical territories and endogamous trans-national communities who have retained unique genetic characteristics.

Result - Scythian: The Scythian region includes present day Southern Russia and neighboring lands. It was here on the Pontic-Caspian steppe that the horse was first domesticated, and this zone has since been home to several mobile horse riding cultures: from the early Kurgan cultures to the Indo-Iranian speaking Scythians and Sarmatians of antiquity to Slavic-speaking Cossacks of today.
