Lactose intolerance is a naturally occurring characteristic of mammals that resulted in earlier weaning times for infants. With cattle domestication, dairy products became readily available. Humans began consuming milk as a regular part of their diet far beyond infancy. Scientists speculate that around this time, a mutation to lactose intolerance occurred, allowing some adult humans to consume milk. In which early human populations would one expect to see the lowest occurrence of this mutation?
populations that do not consume dairy
populations that consume only goat dairy products
