ANTH 1001 : Anthro 1001 Test 2 Notes
Document Summary
Skin pigmentation: pigment is melanin, melanin is produced in melanin. Genetic differences between heavily and lightly melanzied individuals: compared to lightly melanzieed individual, heavily melanzied individual, produces more melanosomes, has larger melanosomes, melanosomes are more dispersed in keratinocyte. Human adaptation to low temperature environments: body shape: bergmann"s rule, body mass is higher in area with lower temperature, allen"s rule, length of arms and legs is shorter in areas with lower temperatures. Human adaptation to low temperature environments: metabolism and blood flow: population living in low temperature environments show an. Extremities adaptation: higher basal metabolic rate, efficient vasoconstriction maintain higher temperature of fingers and toes, population living in high temperature environments show a. Adaptation to low temperature environments: adaptations to low temperature environments by body shape, metabolism, and blood flow are developmental (irreversible) acclimatization. Adaptation to high altitude: hypoxia (i. e. , low atmospheric oxygen levels) is a stress of high altitude. Oxygen transfer between compartments of the body by diffusion.
