Is there a genetic basis for adapting to life at high altitudes? a team of scientists from the united states and china set out to answer these questions. they began their search for a genetic basis for high-altitude hardiness by looking for genes that differed between the tibetan people and closely related, but low-dwelling, neighbors. they collected dna sequence data from 50 tibetans and 40 nearby chinese low-dwellers. for comparison, the scientists also collected dna sequence data from 200 low-dwelling danes, a more distantly related population.

Looking at tibetan highlanders who thrive at high altitudes- normally that would make us sick- they have adapted, 60% oxygen- could pose huge health issue (live with 10% less oxygen in blood than us)

Explanation:

Evolutionary adaptations- involve a change in the genetic makeup to help individuals survive in environment. Tibetans have adaptations to let them function at high altitudes

answer: although many types of viruses can cause a common cold, rhinoviruses are the most common culprit. a cold virus enters your body through your mouth, eyes or nose. the virus can spread through droplets in the air when someone who is sick coughs, sneezes or talks. theres your answer
