Contrary to popular belief, human evolution has not stopped. Our species continues to evolve, both biologically and culturally. Traits such as resistance to certain diseases, the ability to digest milk (lactose tolerance), and adaptations to high altitudes have evolved relatively recently.

Cultural evolution—through science, technology, and global communication—now plays a major role in shaping humanity’s future. While natural selection still operates, human behavior, medicine, and technology have created new pressures and possibilities for evolution.
