How did life begin? And why did it take over a billion years to do... almost nothing? Let’s go back to the Archean Eon, about 4 billion years ago. 🌍 Early Earth wasn’t pretty - it was hot, unstable, and bathed in volcanic gases. Yet somehow, in that hostile chaos… life sparked. 🧬 For something to be alive, it needs three core features: Metabolism – the ability to convert energy and sustain internal processes Reproduction – the ability to make copies of itself Genetic code – a method of storing, transmitting, and mutating information over generations Early microbial life likely emerged in hydrothermal vents, using chemical energy (not sunlight!) to survive. But for nearly a billion years, from ~3.2 to ~2.3 billion years ago, life evolved slowly in what's now called the “Boring Billion.” 🧫 No major diversity. 🧪 No large-scale innovation. Just microscopic organisms getting by - metabolizing, reproducing, and stabilizing. But beneath the surface, critical adaptations were takin...
