The lactase-persistence mutations are roughly as old as the oldest milk-holding vessels or pots
lactase persistence:
Lactase persistence is an example of natural selection, which can cause some humans to continue the activity of the lactase enzyme in adulthood also.
The hereditary examinations and studies propose that the established mutation related to lactase persistence began a long time back, in populaces that started domesticating and dairy cultivation during the Neolithic age when pastoralist populaces started to utilize milk for their livelihood. As found and studied that “the lactase-persistence mutations are roughly as old as the oldest milk-holding vessels.” The cultural and social activities of dairying and drinking non-human milk gave an environment wherein lactase persistence was favorable. DNA proof demonstrates that mutation in the lactase gene emerged in these populaces around a similar time.

Digestion <span>breaks carbohydrates down into basic subunits ("building blocks") called saccharides, or sugars. </span>
It takes place <span>between the alveoli and capillaries, which are located in the walls of the alveoli.</span>
I would say C. Why I say this is because fur is used to keep an animal warm. If the animal no longer needs to be kept warm, then it no longer needs the thick fur.
