“New models show asteroid impacts fractured Earth's crust, forming extensive underground hydrothermal systems that may have fostered early life.”
Recent computer simulations suggest ancient asteroid impacts did more than reshape Earth's surface. They fractured the planet's crust, enabling hot water circulation underground.
These hydrothermal systems created large, long-lasting environments beneath the surface. The conditions within these underground oceans were likely hospitable to early life.
Such hydrothermal networks may have covered much of early Earth's surface, providing numerous niches for life to originate and evolve.
