Organisms can live at high altitude, either on land, in water, or while sed oxygen availability and decreased temperature make life at such altitudes challenging, though many species have been successfully adapted via considerable physiological changes. As opposed to short-term acclimatisation (immediate physiological response to changing environment), high-altitude adaptation.

    Introduction. Ever since Charles Darwin published his book ‘On the Origin of Species by Means of Natural Selection’ nearly years ago (Darwin, ), adaptive evolution has remained a critical research particular interest are insights from hypoxia-tolerant animals – species adapted to oxygen (O 2) poor aquatic or terrestrial environments (Nathaniel et al., ).Cited by: 6.

      A growing body of work is focused on the genetic basis of high-altitude adaptation. Moore et al.

Adaptation to altitude hypoxia is characterized by a variety offunctional changes which collectively facilitate oxygen trans­ port from the ambient medium to the cells of the body.

All of these changes can be seen at one time or another in the course of hypoxic exposure. Yet, as already stressed. Adaptation to altitude hypoxia is characterized by a variety offunctional changes which collectively facilitate oxygen trans­ port from the ambient medium to the cells of the body.

Although the genetic basis of hypoxia tolerance has yet to be fully elucidated in any vertebrate species, evidence from a number of mammals, birds, and amphibians indicates that modifications of hemoglobin function often play a key role in mediating an adaptive response to high-altitude hypoxia (Perutz ).

The unique stress at high altitude is hypobaric hypoxia caused by the fall in barometric pressure with increasing altitude and the consequently fewer oxygen molecules in a breath of air, as compared with sea by: Adaptation to Hypoxia Program (established in ) is currently the longest running Program Project Grant (PPG) in the Lung Division at the NIH/NHLBI.
