Summary:

- This article discusses the discovery of 3.5 billion-year-old rocks in Western Australia that provide new insights into the early history of plate tectonics on Earth.
- The rocks, known as the Pilbara Craton, show evidence of ancient plate tectonic activity, suggesting that this fundamental process was already in place much earlier than previously thought.
- The findings challenge the prevailing view that plate tectonics only emerged around 2.5 billion years ago, and they provide a glimpse into the complex geological processes that shaped the early Earth.
