Human variations in high altitude populations

I managed to maintain my high GPA while holding a job, participating in sports, and Height is centimeters. The Himalayas also have extensive pasture areas which are used by the nomadic and sedentary peoples. In this paper I will describe the high altitude stresses.

Department of Health and Human Services. All these adaptive features very likely have a genetic basis Moore ; Wu and Kayser ; Beall ; Grocott and Montgomery The Tibetans, who have been living in this region for 3, years, do not exhibit the elevated haemoglobin concentrations to cope with oxygen deficiency as observed in other populations who have moved temporarily or permanently at high altitudes.

The thermal protection offered by stone houses seems to be less than that of the adobe structures. The higher regions have pastures where yak, sheep, and goats are the main animals used.

They speak Quechua, which is a branch of the Andean-Equitorial stock. The heart rate then gradually decreases. Origin and basis[ edit ] Himalayas, on the southern rim of the Tibetan Plateau The sickness is compounded by related symptoms such as cerebral oedema swelling of brain and pulmonary oedema fluid accumulation in lungs.

Although this life is hard the people would have it no other way we should respect and commend them for that. The main crops are barley, wheat and buckwheat. The adobe building has a rectangular floor plan with average dimensions of 5 meters by 10 meters.

Essay/Term paper: Human variations in high altitude populations

Shoes would be detrimental during the rainy season because of the extra loss of heat. For example, among four quantitative features, such as are resting ventilation, hypoxic ventilatory response, oxygen saturation, and haemoglobin concentration, the levels of variations are significantly different between the Tibetans and the Aymaras.

It has been shown that Tibetan women with a high likelihood of possessing high oxygen saturation genotypes have more surviving children. In addition, they have high levels mostly double of nitric oxide in their blood, when compared to lowlanders, and this probably helps their blood vessels dilate for enhanced blood circulation.Variation occurs in genetics, skull shape, stature, skin color, etc.

High-altitude adaptation in humans

Human variation is largely structured geographically. Populations that are far from each other, tend to be more different. evolutionary approach to human variation.

The observed indicators of natural selection on EPAS1 and EGLN1 suggest that during the long-term occupation of high-altitude areas, the functional sequence variations for acquiring biological adaptation to high-altitude hypoxia have been enriched in Tibetan populations.
