early Earth
Coverage of early Earth in the Nexus archive.
- Scientists just found a chilling way life may have begun
New experiments suggest freezing and thawing cycles on early Earth may have facilitated the growth and evolution of primitive cell-like structures. Lipid bubbles with different membrane compositions fused into larger compartments, efficiently capturing DNA and potentially enabling complex chemical interactions.
- Meteor impacts may have sparked life on Earth, scientists say
Scientists suggest that asteroid impacts may have created chemical-rich environments on early Earth, potentially sparking life formation. These impact-generated hydrothermal systems could be key in guiding the search for extraterrestrial life.
