A discovery that early Earth was a 'water world' by studying exposed ocean crust
The Earth of 3.2 billion years ago was a "water world" of submerged continents, geologists Benjamin Johnson and Boswell Wing say after analyzing oxygen isotope data from ancient ocean crust, which is now exposed on land in Australia. This discovery could have major implications on the origin of life.
The study demonstrates that geologists can build models and find new, quantitative ways to solve a problem -- even when that problem involves seawater from 3.2 billion years ago that they'll never see or sample.
And, Johnson said these models inform about the environment where life originated and evolved: "Without continents and land above sea level, the only place for the very first ecosystems to evolve would have been in the ocean."
