The human body can adapt to high altitude through both immediate and long-term acclimatization. At high altitude, in the short term, the lack of oxygen is sensed by the carotid bodies, which causes an increase in the breathing depth and rate (hyperpnea). However, hyperpnea also causes the adverse effect of respiratory alkalosis, inhibiting the respiratory center from enhancing the respiratory rate as much as would be required. Inability to increase the breat… Web2 days ago · In recent human evolution, the genetic adaptation of Tibetans to a high-altitude environment is viewed as a classical case [1,2,3].Both genetic and archeological data support the Paleolithic settlement (more than 1000 generations) of Tibetans at high altitudes [4, 5], allowing natural selection to enrich genetic mutations conferring … WebMar 22, 2024 · While evolutionists have traditionally regarded high-altitude adaptation in humans as evidence of natural selection, the new study exposes the complete futility of this Darwinian anti-design paradigm.
