Mediterranean Sea point is in the Calypso Deep in the Ionian Sea. The sea is bordered on the north by Europe, the east by Asia, and in the south by Africa. It is located between latitudes 30° and 46° N and longitudes 6° W and 36° E. Its west-east length, from the Strait of Gibraltar to the Gulf of Iskenderun, on the southwestern coast of Turkey, is approximately 4,000 km (2,500 miles). The sea's average north-south length, from Croatia’s southern shore to Libya, is approximately 800 km (500 miles). The Mediterranean Sea, including the Sea of Marmara (connected by the Dardanelles to
Genetic history of Europe of eastern Asian mtDNA haplogroups, some of which survive in modern eastern European populations. Maternal gene flow to Europe from sub-Saharan Africa began as early as 11,000 years BP, although the majority of lineages, approximately 65%, are estimated to have arrived more recently, including during the Romanization period, the Arab conquests of southern Europe, and during the Atlantic slave trade. A 2007 study by Bauchet, which utilised about 10,000 autosomal DNA SNPs arrived at similar results. Principal component analysis clearly identified four widely dispersed groupings, corresponding to Africa, Europe, Central Asia and South Asia. PC1 separated Africans from the other
