In a new study, a team of researchers suggests that 4 billion years ago, plate tectonics likely looked closer to what we ...

"We see evidence for a significant change on the Earth around 3.8 to 3.6 billion years ago and evolution toward plate tectonics is one clear possibility." Drabon said.

Geology Study reveals 'flawed argument' in debate over when plate tectonics began. Geology North America is 'dripping' down into Earth's mantle, scientists discover.

Significantly, that chronology decouples plate tectonics from the origin of life on Earth: evidence of the earliest single-celled organisms dates back more than 3.6 billion years.

Have tectonic plates changed speed over the last 3 billion years? The answer has far-reaching implications, as plate tectonics affected everything from the supply of vital nutrients for early life ...
