In the ancient rocks of Western Australia's Pilbara region, microscopic crystals have quietly preserved a record of Earth's earliest planetary rhythms. An international research team has read that record and found that plate subduction — the slow, grinding descent of one tectonic plate beneath another — was already operating 3.5 billion years ago, far earlier than many had believed. This discovery reframes how we understand the birth of continents, suggesting that the deep recycling processes which make Earth uniquely habitable were not late arrivals but founding forces, present almost from th
