New geochemical data and molecular-clock analysis suggest life could have arisen during Earth's fiery Hadean period, about 4.4–4.2 billion years ago, with LUCA as the Last Universal Common Ancestor and LECA leading to modern eukaryotes; evidence points to liquid water despite extreme conditions, and ongoing genome recovery efforts may further refine when these ancestral stages appeared.
A new study suggests that Earth's continents began forming much earlier than previously thought, with evidence of active plate tectonics and crust recycling during the Hadean eon, based on chemical analysis of ancient crystals and geodynamic models.
Recent evidence suggests that life on Earth emerged much faster than previously thought, possibly within a few million years of the planet's formation, challenging the long-held view of a hellish, uninhabitable early Earth and emphasizing the need for open-minded research into the origins of life.
