Ancient Lead Exposure Shaped Human Brain Evolution Over Millennia
Lead in the ancient world: a hidden driver of evolution For decades, scientists viewed lead exposure as a modern problem tied to mining, manufacturing, and everyday products. A groundbreaking study published in Science Advances turns that idea on its head, suggesting that our hominin ancestors were intermittently exposed to lead for nearly two million years.…

Ancient Lead Poisoning May Have Shaped Human Evolution
New findings challenge the idea that lead exposure is a modern problem A recent study published in Science Advances proposes a provocative reversal of conventional wisdom: lead poisoning may have been a feature of the evolutionary landscape long before the Industrial Revolution. The international team behind the work argues that lead and other toxic metals…

Could Lead Poisoning Have Shaped Human Evolution? New Research Sparks Debate
Lead, An Ancient Influence: Rethinking a Modern toxin A provocative new study published in Science Advances suggests that lead exposure was not merely a modern problem. Instead, researchers argue that lead and other toxic metals may have subtly shaped the evolutionary trajectory of our species, influencing brain development and even social behavior in ancient humans.…
