Question

Interpret data from multiple populations of humans living long-term at high altitude to describe the adaptations that allow each population to cope and survive with less atmospheric oxygen.

a) Diverse adaptations among populations; no common trends observed
b) Consistent adaptations across populations for survival at high altitude
c) Limited data on adaptations; inconclusive findings
d) No correlation between population locations and adaptations

Answer 1

Adaptations to high altitudes in human populations include increased breathing rate in Tibetans, higher hemoglobin levels in Andeans, and currently unknown adaptations in Ethiopians. These diverse biological responses highlight the resilience and evolutionary variation in humans.

Step-by-step explanation:

Interpreting data from multiple human populations living long-term at high altitudes reveals certain adaptations that enable survival with less atmospheric oxygen. Some of the unique adaptations observed are:

Tibetans exhibit an increased breathing rate.Andean highlanders have higher concentrations of hemoglobin in their blood. Ethiopians living at high altitudes show neither of these adaptations, and their methods of coping with low oxygen levels remain less understood. This diversity in adaptations showcases how different human populations have evolved various physiological responses to cope with environmental challenges like low oxygen levels, leading to a broad array of biological changes and speciation events due to environmental pressures.
