Match the environmental selective pressure with its associated evolutionary adaptive phenotype that resulted because of it.
1.Herding and domesticating animals
2.Migration into northern latitudes with less UV ray intensity, and therefore, less Vitamin D production
3.Prevalence of mosquitos, and therefore, malaria
4.High altitudes, and therefore, less oxygen availability
7.Early reproduction in response to tropical diseases that might cause early death
8.Limited food resources
10.Large variations in temperatures in a single day, such as in the desert (ex: freezing temperatures at night, 100 degrees F during the day)
A."Thrifty genes" that allow people to survive on limited food resources (common tropical islanders). Note: leads to obesity in a high-calorie environment
B.Gene adaptation in gut bacteria that help extract nutrition from seaweed (common in Japanese).
C.Light skin to allow more UV rays to be absorbed by the skin (common in northern Europeans)
D.Genetic adaptations in hemoglobin morphology that allow Hg to bind more oxygen for easier breathing (common in Andeans, Ethiopians, and Tibetans)
E.Small bodies of the pygmy people.
F.Lactose tolerance, or the production of the lactase enzyme, which allows the ability to digest milk from non-human animals, beyond human infancy when human breastmilk is consumed (common in Europeans, Middle Easterners, and Africans)
G.Specific genes to produce enzymes that help people to digest starch more efficiently (common in Asian)
H.A genetic mutation in a metabolism-regulation hormone provides this survival advantage, especially for infants, by modulating the excess energy that is produced when the body temperature rises.
I.Genetic adaptations in red blood cell morphology (ex: sickle-cell anemia, common in Africans)
J.Genetic adaptation that prevents people from losing too much salt in sweat when exposed to high temperatures.
