Publication in Science Advances

How and where did the first forms of life arise? These are the main questions driving research at the Institute of Molecular Evolution at Heinrich Heine University Düsseldorf (HHU). In a new publication in Science Advances, an international team led by Düsseldorf biologists uncovers pioneering insights into the network of chemical reactions that the very first cells used to make the building blocks of life and which sources of energy they used to drive those reactions. They retraced the origin of enzymes during life’s earliest divergence into bacteria and archaea, and found evidence for two independent origins of life for free-living cells.
