This boundary is known as the tree line. The highest-altitude plant species is a moss that grows at 6,480 m (21,260 ft) on Mount Everest. [83]
The Himalayan wolf [14] and the Tibetan mastiff [15] have inherited an altitude-adaptive allele of the gene from interbreeding with a ghost population of an unknown wolf-like canid. The EPAS1 allele is known to confer an adaptive advantage to animals living at high-altitudes.

Acclimatization or acclimatisation (also called acclimation or acclimatation) is the process in which an individual organism adjusts to a change in its environment (such as a change in altitude, temperature, humidity, photoperiod, or pH), allowing it to maintain fitness across a range of environmental conditions.
Animals can be extremely adaptive to limb differences and other disabilities, and soon find ways to work around their limitation. Take this calico kitty, who has twisted forelegs, and has devised ...
