Standard ethnicity estimates compare you to modern reference populations. They answer "what does your recent ancestry look like next to people alive today," usually in broad continental or national buckets, and they mostly reflect the last few hundred to few thousand years.
Our report is different in three ways:
We use only ancient DNA — real genomes from excavated individuals, not modern populations. Your results describe how close you are to people who actually lived in the Greek world and surrounding Balkans thousands of years ago, not to their present-day descendants.
It's regionally fine-grained within Greece and the wider Balkans, instead of giving you one generic "Southern European" or "Greek" percentage.
It traces your genetic layers through time, showing which prehistoric populations — Initial Upper Palaeolithic hunters, Mesolithic foragers, early farmers, Bronze Age Aegeans, Iron Age and Classical communities — contributed most to your profile.
Think of it less as an ethnicity estimate and more as a time-resolved archaeological map of the Greek and Mediterranean world.
