Title:
Early Earth may have been a sunken 'waterworld'

From the article:
"New research shows that the early Earth, home to some of our planet’s first lifeforms, may have been a real-life “waterworld”– without a continent in sight.
The study, which appears March 2 in Nature Geoscience, takes advantage of a quirk of hydrothermal chemistry to suggest that the surface of Earth was likely covered by a global ocean 3.2 billion years ago. It may even have looked a bit like the post-apocalyptic, and land-free, future imagined in Costner’s infamous film Waterworld."
