Scientists have discovered that Neanderthals were more vulnerable to lead poisoning than early modern humans. This fascinating finding could explain why our ancestors managed to outcompete our Neanderthal cousins thousands of years ago.
How Lead Poisoning Shaped Human Evolution
Humans and their ancestors have encountered lead in their environment for over 2 million years. While both groups faced this toxic metal, new research suggests that only humans developed certain adaptations in response. According to scientists, lead exposure may have even played a role in the development of human language abilities. This potential advantage could have contributed to our species’ success and the Neanderthals’ eventual disappearance.
The Competitive Edge Over Neanderthals
Neanderthals’ greater susceptibility to lead’s harmful effects may have negatively impacted their health and cognitive functions. In contrast, humans showed resilience, allowing them to thrive and innovate. This subtle but significant difference may have been a key factor in our evolutionary journey.
