  • Resumen
    • Brahic offers a beginner's guide to the origin of life. Here, she predicts when and where did life begin and what was the first life like. Assuming life didn't arrive on Earth via meteorites, it must have popped up in the last 4.5 billion years, after Earth formed. However, there are clear traces of single-celled life from 3.5 billion years ago, so it must have been before that. Charles Darwin suggested that the beginning of life might have happened in "some warm little pond". Many biologists think life began as RNA molecules, which can both carry genes and use chemical reactions to gain energy.
