The CODNA haplotree reflects an overview of the current Y-DNA results in the FTDNA project. The MRCM (most recent common mutation) IJK-L15 occurred more than 45.000 years before present somewhere in the Middle East [FTDNA Globetrekker].
The interest for the Y-DNA haplogroups in CODNA project starts about 4.500-5.000 years before present with:
The project originated in research into family roots in Terjärv, a district of the Municipality of Kronoby in Ostrobothnia, but has since expanded to encompass a wider region.
The current CODNA Geographical Area of Interest covers mainly the Central Ostrobothnia region but also surrounding areas where genetic genealogy connections can be found.

The CODNA results can be found in Central Ostrobothnia DNA Project at FTDNA.
