K1a2 is a common mtDNA haplogroup in European Neolithic samples (2 out of 5). The Aegean is the likely origin of European Neolithic farmers. Principal component analysis (PCA) revealed a tight clustering of all five Aegean Neolithic genomes with Early Neolithic (EN) genomes from central and southern Europe.

PCA of modern reference populations (18, 19) and projected ancient individuals. The Greek and Anatolian samples reported here cluster tightly with other European farmers close to modern-day Sardinians; however, they are clearly distinct from previously published Caucasian hunter-gatherers (20).
