Earth's Northern Lights typically dance near the poles, but 41,000 years ago, they lit up skies over North Africa and Australia. New research reveals how dramatically Earth's magnetic field weakened and shifted during an event called the Laschamps geomagnetic excursion, potentially influencing human evolution at a pivotal moment in our history...
During the Laschamps excursion, Earth's magnetic field weakened to just 10% of its current strength, while the magnetic poles shifted dramatically away from the geographic poles...
Using advanced computer modeling, the research team reconstructed Earth's magnetosphere during five key periods of the excursion. At its peak around 40,977 years ago, Earth's protective magnetic bubble shrank dramatically – from its normal extent of 8-11 Earth radii (51,000-70,000 km) to just 2.43 Earth radii (15,498 km).
The magnetic field also transformed from a simple north-south configuration to a complex arrangement with multiple magnetic poles scattered around the planet...
The Laschamps excursion coincided with a critical period in human history – as modern [sic] humans (Homo sapiens) spread throughout Europe, Neanderthals disappeared, [sic] and humans created the first known cave art [sic]...
Modern humans also invented tailored clothing during this period, with archaeological sites containing not just hide scrapers but also sewing implements like needles and awls. This clothing would have allowed for greater mobility while providing coverage and potentially protection from increased radiation.

‘ How in the world am I ever able to discern which of either is even close to the truth?’
You’ve answered that question already.
Ask your god.
Get back to everyone with whatever answer you get.
Well, If I am hearing him correctly, he is saying be skeptical, very skeptical. I believe I even provided that already as my take on what I am being told as being the truth.
> As you can see, it presents a far different answer to the study you presented. How in the world am I ever able to discern which of either is even close to the truth?
That isn’t different at all. The general response you got is, magnetic reversals happen, and it isn’t dependent on whether you believe it or not.
The three earlier FR topics linked above show the basis for this particular one, which is the ‘fossil’ magnetic field direction in some 41-42K year old dead trees in NZ. Instead of just generating chaff, your time would have been better spent reading up instead of complaining. But clearly that’s your jam, because you have no interest in this topic.
