Did Life Start When Impacts Created Vast Hydrothermal Systems in Earth's Crust?
New research suggests that asteroid impacts during Earth's early history may have created hydrothermal systems that served as the 'chemical kitchen' for the origin of life. These impacts likely delivered essential prebiotic molecules and created porous rock environments suitable for chemical reactions.
Why it matters
This research offers a compelling scientific hypothesis for how life began on Earth, shifting the perception of asteroid impacts from purely destructive to potentially creative.
In most people's minds, asteroid strikes are associated with destruction and carnage. They can correctly point to the Chicxulub impactor that wiped out the dinosaurs, even if they don't know the impactor's name. Contemplating the crater-saturated surfaces of the Moon, Mercury, and other worlds only strengthens the link between impacts and destruction.
