Could life on Earth have arrived from the stars? Scientists are taking the question seriously
Life on our planet emerged quickly or, at least, it did so on a geological timescale. Fossils reveal that micro-life existed on our planet at least 3.5 billion years ago. The rapid emergence of life ...
Around 2.3 billion years ago, the Great Oxygenation Event (GOE) marked a major turning point in Earth’s history. The increase ...
Compared to previous theories, the current research emphasizes the complexity of the biological and chemical processes that brought about life.
