How the first biomolecules could have been formed

International team shows that the first biologically relevant compounds could have originated on Earth's surface

14-Jun-2022

The chemical precursors of present-day biomolecules could have formed not only in the deep sea at hydrothermal vents, but also in warm ponds on the Earth's surface. The chemical reactions that may have occurred in this “primordial soup” have now been reproduced in experiments by an international ...
