What are examples of three adaptations in humans?

1 example would be weather, we adapt to the weather with being in it. 

Another could be we all used to be allergic to lactose, a type of sugar in milk. But we adapted to it since we domesticated animals.

Another one could be pigmentation. People living in the sun a lot or for their lives and adapted to turning their skin darker colors to prevent the sling from burning.

If these are the missing choices: a. to determine skin temperature, place the back of your hand against the patient's skin.b. determine body temperature by touching the patient's hands and feet.c. skin temperature will tell you very little about this patient's condition or well-being.d. the patient's skin temperature and color will likely be warm and red.my answer is: a. to determine skin temperature, place the back of your hand against the patient's skin. using the back of the hand to check for temperature rather than the palm is more effective because the back of the hand has more nerves that can feel and transmit the temperature than the palm.
