15. Adaptation to Air Pollution
With urbanization and industrial growth, air pollution has become a constant environmental pressure. Early research suggests that some human populations may be evolving increased resistance to airborne toxins, especially in cities with persistent smog and high pollution levels.
Gene variants linked to lung function and toxin breakdown are being studied for their roles in protecting against the harmful effects of polluted air. Though this adaptation is still emerging, it highlights how human evolution continues to respond to modern challenges and changing environments. National Geographic
