Question

Quizplus · Accepted Answer

The different traits exhibited by people living in high altitudes illustrate adaptive evolution, as their biology has been reworked through natural selection to better suit their environment. The other options do not fit as well - stabilizing evolution refers to a reduction in variation within a population, sexual selection involves the selection of certain traits for mating purposes rather than survival advantage, and acclimatization refers to a temporary physiological response to changes in the environment.
