UV Radiation, Clothing, and Neanderthal Extinction
Long ago, Neanderthals vanished, while humans lived on.
Scientists think one reason could be the Earth's magnetic field weakening, letting in more sun rays.
Humans used 'sunscreen' (pigments) and snug clothes, unlike Neanderthals, who might have been more exposed.
This, along with climate changes, could have made it harder for Neanderthals to survive.
It's still a mystery, but scientists are exploring how these differences could have played a role in who lived and who died.
Weakening of Earth's magnetic field around 40,000 years ago coincided with Neanderthal extinction.
The weakened magnetic field increased exposure to harmful ultraviolet radiation.
Homo sapiens used mineral pigments (ocher) as sunscreen and wore form-fitting clothes.
Neanderthals may have worn looser clothing and lacked sunscreen practices.
Researchers suggest these differences may have contributed to Neanderthal demise and human survival.
- Who
- Neanderthals and Homo sapiens (humans).
- What
- Weakening of Earth's magnetic field and increased UV exposure potentially contributed to Neanderthal extinction.
- When
- Around 40,000 years ago, during the Laschamps event.
- Where
- Northern and southern latitudes, including areas where Neanderthals and Homo sapiens lived.
- Why
- Increased UV radiation exposure, possibly combined with other factors, may have disadvantaged Neanderthals.

UV Radiation role
Researchers Hypothesis
UV radiation played a significant role in the demise of Neanderthals.

It is also possible that this was just a coincidence of timing
