      Abstract: The Balkan Peninsula is a complex cultural mosaic comprising
      populations speaking languages from several branches of the
      Indo-European family and Altaic, as well as culturally-defined
      minorities such as the Aromuns who speak a Romance language. The
      current cultural and linguistic landscape is a palimpsest in which
      different peoples have contributed their cultures in a historical
      succession. We have sought to find any evidence of genetic
      stratification related to those cultural layers by typing both mtDNA
      and Y chromosomes, in Albanians, Romanians, Macedonians, Greeks, and
      five Aromun populations. We have paid special attention to the
      Aromuns, and sought to test genetically various hypotheses on their
      origins. MtDNA and Y-chromosome haplogroup frequencies in the Balkans
      were found to be similar to those elsewhere in Europe. MtDNA sequences
      and Y-chromosome STR haplotypes revealed decreased variation in some
      Aromun populations. Variation within Aromun populations was the
      primary source of genetic differentiation. Y-chromosome haplotypes
      tended to be shared across Aromuns, but not across non-Aromun
      populations. These results point to a possible common origin of the
      Aromuns, with drift acting to differentiate the separate Aromun
      communities. The homogeneity of Balkan populations prevented testing
      for the origin of the Aromuns, although a significant Roman
      contribution can be ruled out. [ABSTRACT FROM AUTHOR]
