From the oxygen-thin peaks of the Himalayas to the crushing depths of ocean floors, human bodies have evolved remarkable abilities to thrive where other species can't. Scientists are uncovering how these adaptations reveal the incredible flexibility built into our biology.
The largest study of ancient human DNA reveals that human evolution has dramatically accelerated since farming began, reshaping everything from disease resistance to physical appearance. Scientists found nearly 500 gene variants that changed through natural selection as our ancestors adapted to revolutionary lifestyle changes.
Ancient humans in China crafted sophisticated stone tools during a brutal ice age, proving creativity thrives under pressure. The discovery rewrites what we thought we knew about early human innovation.
A Duke scientist's new book reveals how our bodies constantly adjust to different environments, from deep-sea diving to high altitudes. Understanding this shared human adaptability could fight dangerous health misinformation.
Researchers finally solved a mystery millions of years in the making: why humans evolved to be awake during the day while most early mammals were nocturnal. The answer lies in tiny cellular switches that respond differently to daily temperature changes.
Living human neurons grown on a computer chip mastered the classic video game Doom in seven days, marking a massive leap toward biological computers that could one day control robotic limbs. The breakthrough shows that brain cells can handle complex, real-time decisions far faster than traditional AI.
Scientists discovered tiny genetic "switches" that shaped human language ability before we split from Neanderthals. These ancient regulators still influence how we learn and use language today.
Scientists discovered that male Neanderthals and female humans formed most ancient relationships, solving a 20-year genetic mystery. The finding reveals how social choices shaped human evolution.
New fossil discoveries reveal how our uniquely powerful thumbs helped make us human. The evolution of our hands may be just as important as our big brains in shaping who we became.
Scientists discovered ancient human ancestor fossils in Morocco dating back 800,000 years, revealing that North Africa played a central role in human evolution. The findings are transforming our understanding of how early humans lived, worked, and mourned their dead.
Four astronauts launched aboard NASA's Artemis 2 mission on April 1, marking humanity's first return to lunar orbit in over five decades. The crew will travel farther into space than any humans before them during their historic 10-day journey.
Four astronauts aboard NASA's Artemis 2 mission crossed into the moon's gravitational sphere on April 6, becoming the first humans to reach lunar space since 1972. Tonight, they'll break the distance record for human spaceflight.
The United Nations just launched a worldwide coalition to put human rights at the center of global decision-making. The Global Alliance for Human Rights unites governments, businesses, faith leaders, and everyday citizens around a shared vision of justice.
Actor Ethan Hawke delivered a moving explanation of why AI can never replace human creativity, describing his daughter's imperfect art as more valuable than any AI-generated masterpiece. His response is resonating with millions who worry about technology replacing human expression.
A newly excavated cave in Israel reveals that Neanderthals and early humans didn't just cross paths—they shared tools, burial practices, and possibly symbolic rituals. This discovery rewrites our understanding of early human cooperation.
Four astronauts just broke the record for the farthest distance humans have ever traveled from Earth, soaring past the Moon and witnessing views no one has seen before. The Artemis II mission marks a giant leap toward humanity's return to the Moon and eventual journey to Mars.
Archaeologists in central China discovered sophisticated stone tools dating back 160,000 years, proving early humans in East Asia were just as technologically advanced as their African and European counterparts. The find challenges decades of assumptions about ancient human ingenuity.
New discoveries at an Israeli cave reveal that Neanderthals and early humans didn't just coexist—they collaborated, shared tools, and even buried their dead together. This groundbreaking find rewrites our understanding of human evolution as a story of cooperation, not competition.
Scientists extracted proteins from 400,000-year-old teeth and discovered evidence that our ancient ancestor Homo erectus may have interbred with other human relatives, passing genes that still exist in some people today. This breakthrough shows how modern humans carry traces of ancestors who walked the Earth hundreds of thousands of years ago.
Scientists have created the first global map of how genetics and geography shape everything from aging to gut health. The groundbreaking study could transform how doctors treat patients from different backgrounds.
