Other than the absurdity of racial classifications in and of itself, this doesn't make sense. And it's false. Finland is notably more differentiated from Norway/Sweden than Greece/Italy is from Turkey. The cline from the Ionian to the Aegean Sea is smooth and gradual. The cline from Finnmark/Norrbotten is more abrupt and this is in regards to FINNS, let ALONE the Saami.
There's also isn't major differentiation between ANY part of Greece vs ANY part of Turkey or between parts of Turkey vs other parts of Turkey. That's also not supported by evidence.
