Originea vieții pe Pământ poate fi o surpriză. Misterul bacteriilor vechi de 8.000.000 ani revenite la viață • Newsweek România

The revival of 8 million-year-old bacteria from Antarctic ice raises questions about the origins of life on Earth, suggesting extraterrestrial influences. Researchers from Rutgers University found that microorganisms, trapped in ancient ice, could resume metabolic activity after being dormant for millennia. This discovery reignites interest in the panspermia theory, which posits that life may have originated from elsewhere in the cosmos. The study indicates that DNA viability decreases significantly over time, establishing a time limit for biological transport between celestial bodies. If life did arrive on Earth from space, it must have done so within a few million years before DNA degradation rendered it non-viable.
