Earth’s Shield Nearly Failed—Life Got Wild

Imagine Earth almost losing its magnetic shield 591 million years ago—turns out, that close call may have sparked the rise of complex life! Scientists found that when the magnetic field weakened, more oxygen flooded the planet, letting weird, soft-bodied creatures thrive. If the shield hadn’t bounced back, we might’ve ended up like Mars. Basically, Earth’s near-disaster may have been the ultimate plot twist for life as we know it! #EarthHistory #ScienceNews #Evolution #MagneticField #LifeOnEarth #Science
