As a milk stand enthusiast, you are interested in the evolution of lactase persistence around the world. You examine overall population numbers in the United States, as well as estimates of lactase persistence rates based on medical records and research data. For comparison, you repeat these methods using data from Japan and Saudi Arabia. Assuming lactase persistence is determined by DNA, which population, if any, are evolving with respect to lactase persistence? (select the one best answer) Percent lactase persistent in 1925 Population in 1925 Percent lactase persistent in 2025 Population in 2025 Japan ~7% 60 million ~7% 123 million Saudi Arabia ~55%  1 million ~55% 35 million United States ~85% 116 million ~75% 344 million *numbers in this table differ from those in the version shared in the review session and practice questions
