Scientists Project How Humans May Evolve Over the Next Millennia

Researchers say that human evolution is now shaped by a mix of genetics, environment and rapidly advancing technology. Urbanisation, diet changes and widespread medical interventions are already influencing traits such as jaw size and immune responses. Gene‑editing tools, advanced prosthetics and artificial intelligence could further steer human physiology, while climate change and potential interplanetary migration add long‑term selective pressures. Over the next century changes are expected to be subtle, affecting posture, hand dexterity and disease resistance. Over many centuries or a thousand years, more pronounced shifts could appear in skeletal structure, lung capacity and skin pigmentation, though such projections remain theoretical and depend on future technological and environmental developments.
