Question

What evidence is there for the hypothesis that lactase persistence arose independently in populations in Northern Europe and East Africa? (Select the best answer) different single base mutations in a lactose regulatory region of DNA 5 to 9 thousand year old potsherds contain traces of milk fat! lactase persistence is common in certain European and African populations the dates for the origins of lactase persistence mutations are similar to archeological dates for the origin of cow milk! consumption

Answer 1

The dates for the origins of lactase persistence mutations are similar to archeological dates for the origin of cow milk consumption.Around 8000 years ago when human jst started milking newly domesticated cows , the mutations started to occur and became more frequent and gradually established lactase persistence.
