Edited sentence: About 40% of all clades of M1 found in Europe are M1a and consequently of recent East African origin.At least 7.2% of European Males carry the African Haplogroup.At the Strait of Gibraltar, Africa and Europe are separated by only 15km of Ocean.At the Suez, Eurasia is connected to Africa.But Europe was periodically accessible by Africans due to fluctuations in the size and climate of the Sahara.Haplogroup M1 is also found in Europe at low frequencies, but it is not uncommon in Southern Europe.However, one clade of haplgroup M1, M1a is widely accepted to be of East African origin.In a study by Gonzalez et al 2007, haplogroup M1 had an overall frequency of 0.3% in the samples that were analyzed.It's origins are thought to lie in the region of the Horn of Africa but the main clades present in Europe are:.The Mediterranean Sea and the Sahara Desert were formidable barriers to gene flow between Sub-Saharan Africa and Europe.The Nile river valley, which runs from East Africa to the Mediterranean Sea served as a bidirectional corridor in the Sahara desert, that frequently connected people from Sub-Saharan Africa with the peoples of Eurasia.The highest frequencies were found in Sicily where 3.8% of the population were members of haplogroup M1.The origins of haplogroup M1 have yet to be conclusively established.These haplogroups included L1b, L2a, L3b, L3d and M1, of which L1b, L3b1, L3d appeared to be of West African origin.have remarked that E1b1b seems to represent a late-Pleistocene migration from Africa to Europe over the Sinai Peninsula in Egypt
