• Ancient Scottish meteorite impact aligned with Earth’s first land ecosystems

    Around 1 billion years ago, a meteorite collided with Earth, leaving behind a trail of clues in the rocks of northwest Scotland. This event may have shaped the earliest forms of life on land. By studying minerals trapped in ancient rock layers, scientists now suggest that the impact could have altered the environment in ways that influenced microbial ecosystems. The findings open new questions about the role of such collisions in Earth’s early biological history.
