Weird space weather seems to have influenced human behavior on Earth 41,000 years ago – our unusual scientific collaboration explores how
Two geophysicists and an archaeologist teamed up to connect space weather 41,000 years ago to human behaviors that might have been in response – and show the value in cross-discipline teamwork.

With the weakened magnetic field, more harmful radiation would have reached Earth's surface, elevating risk of sunburn, eye damage, birth defects, and other health issues.
In response, people may have adopted practical measures: spending more time in caves, producing tailored clothing for better coverage, or applying mineral pigment "sunscreen" made of ochre to their skin. As we describe in our recent paper, the frequency of these behaviors indeed appears to have increased across parts of Europe, where effects of the Laschamps Excursion were pronounced and prolonged.
