6,000 years of dairying in Africa

New research shows dairy consumption in eastern Africa began before the evolution of lactase persistence
Got milk? The 1990s ad campaign in the US highlighted the importance of milk for health and wellbeing, but when did we start consuming the milk of other animals? And how did the practice spread? A new study led by scientists from Germany and Kenya highlights the critical role of Africa in the story of dairying, showing that communities there were using milk by 6,000 years ago.

An international team led by researchers at the Max Planck Institute for the Science of Human History in Jena, Germany and the National Museums of Kenya (NMK) in Nairobi, Kenya, analyzed human remains from 41 adult individuals from 13 ancient pastoralist sites excavated in Sudan and Kenya and, remarkably, retrieved milk proteins from eight of the individuals. Researchers can detect milk proteins in denta ....

Dairy Farming in Africa Dates Back at Least 6,000 Years

Dairy Farming in Africa Dates Back At Least 6,000 Years
JENA, GERMANY
Science Magazine reports that scientists examined the dental calculus from the teeth of eight skeletons unearthed in Sudan and Kenya that were dated to between 2,000 and 6,000 years old. The presence of milk proteins in the hardened plaque indicates that the people had consumed milk products such as milk, cheese, or yogurt at least 6,000 years ago. However, an earlier study of DNA extracted from these remains did not detect the genes that would have allowed the adults to digest milk products. “It looks like the community was drinking milk before they had lactase persistence,” said team member Madeleine Bleasdale of the Max Planck Institute for the Science of Human History. Fermenting the milk may have made it easier for early farmers to digest, she added. When lactase mutations evolved, however, they spread rapidly, since the ability to digest milk products offers a better chance of survival ....

Ancient Proteins Help Track Early Milk Drinking in Africa

Tracking milk drinking in the ancient past is not straightforward. For decades, archaeologists have tried to reconstruct the practice by various indirect methods. They have looked at ancient rock art to identify scenes of animals being milked and at animal bones to reconstruct kill-off patterns that might reflect the use of animals for dairying. More recently, they even used scientific methods to detect tr ....

Jan. 27 (UPI) The extraction and analysis of milk-specific proteins from ancient materials, including dental calculus, has allowed scientists to uncover the origins of dairying in Eastern Africa.
Some 6,000 years ago, toothbrush technology was non-existent. As a result, the teeth of early humans accumulated significant amounts of plaque. These mineralized layers of ancient plaque, hardened by time, form what s called calculus.

Humans were drinking milk before they could digest it

Our history with milk presents a chicken-or-egg conundrum: Humans couldn’t digest the beverage before they evolved mutations that helped them do so, yet they had to already be consuming milk to change their DNA. “There’s always been the question of which came first,” says University of Pennsylvania geneticist Sarah Tishkoff. “The cultural practice or the mutation.” ....
