life's origins

Life's origins likely began around 3.5 to 4 billion years ago with simple molecules forming in Earth's early environment. These molecules gradually organized into self-replicating entities called protocells, which could pass on information and metabolize nutrients. Over time, these structures evolved increasing complexity, eventually giving rise to the first true living organisms. This process, driven by chemical reactions, natural selection, and environmental factors, set the foundation for all life today, ranging from microbes to plants and animals. While many details remain unknown, researchers continue to uncover clues about how inanimate chemistry transitioned into living systems.
