Short-term adaptations to the stress of high
altitudes include a breathing and heart rate increase of up double even while resting
resulting in an increase of blood pressure and pulse rate as the hearts pumps
harder to get more oxygen.
A facultative adaption to high altitude is
the process of acclimatization when a person born at a low elevation travels to
a high elevation within

High altitude born natives have the
developmental adaption of developmental acclimatization in which the natives
grow slower and mature later than those in lower elevations as well as being
more efficient at diffusing oxygen from blood to body tissues.

The study of human variation and explorations
has lead to the discovery of mutations such as the one found in Tibetans EPAS1.
The study of mutations like EPAS1 can help in the creation of vaccines and
medications for issues like oxygen deficiency or reproduction problems such as
maternal death caused by preeclampsia.

Race could be used as an example of the Tibetans
and the EPSA1 being passed on within the Tibetans that allowed them to adapt to
the higher altitudes while still having normal levels of hemoglobin. Environmental
influences better explains adaption’s in human variations because the adoptions
do not alter for certain races it stays the same throughout each one.
