Once-Green Sahara Hosted Early African Dairy Farms
The sandy dunes of the Sahara may seem an unlikely place for a dairy farm, but about 7,000 years ago, herders tended and milked cattle in what is now desolate desert, new research shows.
About 10,000 years ago, the Sahara desert went through a phase called the Holocene African Humid Period. Fossilized bones show that by the sixth millennium B.C., cattle, sheep and goats roamed over green savanna, and rock art depicts cows with full udders. The occasional image even shows milking, said study researcher Julie Dunne. By analyzing pottery fragments, Dunne and her colleagues have now shown that these early herders were not only milking their livestock, but also processing that milk into products like yogurt, cheese and butter.
