3 000 years to adapt to altitude: Tibet

It took only a few thousand years for Tibetans to develop gene mutations that help them cope with low oxygen levels at high altitudes, a new study found.

The widespread mutation in Tibetans occurs near a gene called EPAS1, which codes for a protein involved in sensing oxygen levels and may also help balance aerobic and anaerobic metabolism.
