apr 5, 1922 - Russian biochemist Alexander Oparin
Description:
hypothesizes that life on Earth began in a “primeval soup” of matter and water between 3.9 and 3.5 billion years ago, as chemical reactions produced small organic molecules from substances present in the atmosphere, which were then organized by chance into the more complex organic molecules that are the basis of life.Added to timeline:
