According to The Department of Immunology and Molecular Biology, H. 12 de Octubre, Universidad Complutense, Madrid, Spain- “HLA genes in Macedonians and the sub-Saharan origin of the Greeks “
Greeks are found to have a substantial relatedness to sub-Saharan (Ethiopian) people, which separate them from other Mediterranean groups. Both Greeks and Ethiopians share quasi-specific DRB1 alleles, such as *0305, *0307, *0411, *0413, *0416, *0417, *0420, *1110, *1112, *1304 and *1310. Genetic distances are closer between Greeks and Ethiopian/sub-Saharan groups than to any other Mediterranean group and finally Greeks cluster with Ethiopians/sub-Saharans in both neighbour joining dendrograms and correspondence analyses. The time period when these relationships might have occurred was ancient but uncertain and might be related to the displacement of Egyptian-Ethiopian people living in pharaonic Egypt.
Also the sickle-cell anemia or malarial-immune engrams, which the littoral Greek and African populations are medically known to share!

SECOND AND THIRD GENERATION RACIAL MIXES IN ANCIENT TIMES
Both Aristotle and Plutarch discuss the racial characteristics of of second and third generation black-white racial mixes in their works:
“Further, children are like their more remote ancestors from whom nothing has come, for the resemblances recur at an interval of many generations, as in the case of the woman in Elis who had intercourse with the Aethiop; her daughter was not an Aethiop but the son of the daughter was.” - Aristotle, Gen. An. 1.18.722A
“But parents may pass on resemblance after several generations, as in the case of the woman in Elis, who committed adultery with a negro; in this case it was not the woman’s own daughter, but the daughter’s child that was a blackamoor” - Aristotle, Hist. An; 7.6.586A.
Further references to racially mixed types stretching over generations can be found in Plutarch’s De Sera Numinis Vindicta, 21.
Also previously mentioned was the herm of Memnon, which, according to Graindor, was a Negroid pupil of Herodes Atticus. This herm is ”of mongrel race but with the Negro type of North Africa, Nubia or Abyssinia, being prevalent.”(”“de race métisse mais avec prédominance du type nègre du Nord de l’Afrique, de la Nubie ou de l’Abyssinie.” - GRAINIDOR, P., 1915 Tête de Nègre du Musée de Berlin. Bulletin de Correspondance Hellénique, 39, p. 402.)
CONCLUSION
This brief overview shows conclusively that:
1. The Ancient Greeks were well aware of the Negroid and mixed racial types;
2. That Blacks were present, as slaves, mercenaries or freedmen, in Classical Grecian times;
