During the next days or weeks I am going to run several Treemix-analyses targeting to regional migrations among present-day Europeans. My first run figures migrations in Finland, but please keep on following this work, because I'll do several analyses covering most regions in Europe and neighboring areas.
What we see in Finland (as derived from the result)
- prehistoric Germanic migration to Southwest Finland
- Swedish migration to Finland
- post-Tavastian migraton to Estonia
- Finno-Ugric (pre-Finnic) migration to Komi (which definitely indicates Komi being a mixed Finno-Ugric population with European root of another kind
Post-Tavastian likely means the age before Finland was populated by present-day Finns.
There is also a migration from France to Poland, but solving it needs more western and Central European samples. Next runs will be more focused on this issue.
This Treemix run was executed using global setting, with no root and the migration count 5.
