Genetic signatures of high-altitude adaptation in Tibetans PNAS
WebbTibetans suffer no health problems associated with altitude sickness, but instead produce low levels of blood pigment ( haemoglobin) sufficient for less oxygen, more elaborate blood vessels, [21] have lower infant mortality, [22] and are heavier at birth. [23] EPAS1 is useful in high altitudes as a short term adaptive response. Webb12 apr. 2024 · The Tibetan Plateau, as the world’s highest and largest plateau, represents one of the most inhospitable global environments to which humans have adapted.
