Plate Tectonics Not Required for the Emergence of Life

Plate tectonics involves the horizontal movement and interaction of large plates on Earth’s surface. New research indicates that mobile plate tectonics—thought to be necessary for the creation of a habitable planet—was not occurring on Earth 3.9 billion years ago.

The finding contradicts previous assumptions about the role of mobile plate tectonics in the development of life on Earth. New finding contradicts previous assumptions about the role of mobile plate tectonics in the development of life on Earth. Moreover, the data suggests that ‘when we’re looking for exoplanets that harbor life, the planets do not necessarily need to have plate tectonics,’ says the lead author of a new paper.
