Question

Even though lactose intolerance is found in only about 10% of current northern Europeans, researchers studying 7,000-year-old fossil remains of ancient European populations found that most were lactose intolerant. What conclusion might you draw from this evidence?

Answer 1

The correct answer is - natural selection caused the rapid mutation for lactose intolerance and mutation can arise any time.

Step-by-step explanation:

Lactose intolerance is found in the 10% of the northern Europeans and researchers studying fossils that are 7000 years old that shows that most of them were lactose intolerant.

According to study it can be explained that the mutation can arise for tolerance spontaneously in any population as it occur 7000 years ago. It must become prevalent due to the natural selection process.

Thus, the correct answer is - natural selection caused the rapid mutation for lactose intolerance.
