Radical racists views circulate from the so called (FYR)Macedonia Encyclopedia.

New incredible provocation contained in the so-called "Macedonians Encyclopedia, which have written, at the behest of the extreme-right Prime Minister Gruevski, the historians of the Academy of Sciences and Arts of Skopje and presented himself with all solemnity on 16 September[1] . The two-volume work of 1671 pages, the version of which was financed by public funds of this Multietnnic Balkan new born State, according to Mr. Gruevski is absolutely express “the cultural and political past and our present”, the Skopje government not only tries to rewrite history region at will, but consciously alter key elements of Greek national status.
Specifically, on page 67 of the encyclopaedia and under the word "Greek" states that "recent research has shown that the Greek nation as having been descended from black African tribes of the Sahara desert!"
The 260 Slav Macedonians historians, bringing out the government arranged the shipment was, they note that the Greeks, coming from the continent, with virtually cultural backgrounds, "settled by the local appropriating Balkan cultures, which were advanced and shown as its own achievements."
The unprecedented provocation of Skopje government reaches in the point to characterize the Greek culture as result of counterfeiting and intercepting other cultures, while not hesitating to seize the historic Parthenon and even the Homeric epics! "Even the epics of Homer and the Parthenon is not the result of Greek culture, but as result of counterfeiting, adoption and even interception of these local indigenous cultures such as ours, the Macedonia!"
Slav Macedonian academics base theirs view in a paper [2] that have published from a Spanish lab with the corporation of three Slav Macedonians genetic scientists. This paper had concluded that "Greeks are found to have a substantial relatedness to sub-Saharan (Ethiopian and West African) people, which separate them from other Mediterranean groups." The conclusions of the paper were related to the "Black Athena" debate and became embroiled in disputes between Greek and Slavmacedonians nationalists.
Shortly after this, three respected geneticists, Luca Cavalli-Sforza, Alberto Piazza and Neil Risch, argued that the scientific limitations of Arnaiz-Villena's methodology.[3] They stated that "Using results from the analysis of a single marker, particularly one likely to have undergone selection, for the purpose of reconstructing genealogies is unreliable and unacceptable practice in population genetics.", making specific allusion to the findings on Greeks (among others) as "anomalous results, which contradict history, geography, anthropology and all prior population-genetic studies of these groups."
Arnaiz-Villena countered this criticism in a response, stating "single-locus studies, whether using HLA or other markers, are common in this field and are regularly published in the specialist literature" .
No multiple-marker analysis has ever duplicated Arnaiz-Villena's results. In The History and Geography of Human Genes (Princeton, 1994), Cavalli-Sforza, Menozzi and Piazza grouped Greeks with other European and Mediterranean populations based on 120 loci . See the below MDS plot



Then Aryub [4] did the same thing using 182 loci and again no sub-Saharan admixture was detected in the Greek sample. Another study was conducted in 2004 at Skopje's University of S. Kiril and Metodij, using high-resolution typing of HLA-DRB1 according to Arnaiz-Villena's methodology. Contrary to Arnaiz-Villena's conclusion, and no sub-Saharan admixture was detected in the Greek sample.[5]
It seems that even the last study that conducted from FYROM University averted Slav Macedonians of the FYROM to write such as racists comments as regards the Greek nation and the ancient Greek civilization. The disputed data continues to be cited all over the internet, mostly by white supremacists, afrocentrists and Slavmacedonians nationalists (usually VMRO fans and Diaspora Centers like maknews.com) who have political motivations to relate modern and/or ancient Greeks to black Africans.
But now officially FYROM administration adopted these radical views and publish a encyclopaedia that flourish of lies, accuracies and racists views. The genetics, with its appearance of scientific objectivity, holds obvious—albeit illusory—appeal. As Appelbaums [6] remarked for nations with strong claims to territorial sovereignty, genetic data will be irrelevant; for nations with weak claims, such data will always be inadequate. Advocates who look to genetics for a decisive victory are certain to be disappointed.
Nationality is a matter of culture and education and not genetic (mixtures) issue. Who is the person that put blood standards as about the nationality (race)?
The racistS and the "white arryan" supremacistS that think the colour of the skin and eye or the blood markers are the definition of the race.
Modern Greeks are the descendants of all the peoples who have adopted and retained that language and that civilization from classical times to the present. I am not claim that genetic purity is an ideal for the Greek people and the others racist thinks.Asa I said even Sforza put two others factors except the clusters and these are the language and the history. Modern Greek nation is not an entirely modern formation, for it is based on much older cultural groups (ethnies). Greek ethnies (like Arvanites, Vlachs, Slavophones etc.) present "permanent cultural attributes" such as memory, value, myths and symbolisms. Greek ethnies present a common cultural origin descending from ancient Greece and Byzantium. Thus, as Smith points out, "the challenge for scholars is to represent more accurately and convincingly the relationship of ethnic, cultural (Greek) past to modern (Greek) nation". [7]
