Zitat:und kam auf arabische und türkische Seiten,teilweise Zeugs,das so aussah,daß ich es lieber nicht aufgemacht hab. Entweder der veräppelt die Leut oder er versteht uns eh nicht.

Zitat:The second center of adult lactase persistence lies in the arid lands of Arabia, the Sahara, and eastern Sudan. There, lactase persistence characterizes only nomadic populations heavily dependent on camels and cattle, such as the Bedouin Arabs, the Tuareg of the Sahara, the Fulani of the West African Sahel, and the Beja and Kabbabish of Sudan. Lower rates among Nigerian Fulani may indicate a higher degree of genetic mixing with other peoples than among the Fulani of Senegal. In contrast, surrounding urban and agricultural populations, whether Arab, Turkish, Iranian, or African, have very low rates. It is interesting to note that the Somali sample also had a low frequency of the LAC*P allele. Possibly, pastoral Somali have higher prevalences than their urban compatriots.
