LIO, in collaboration with the Laboratory of Geology of Lyon (LGL ), is investigating the origins, formation, and evolution of life and, on a larger scale, of the Earth and other planets.

The study of the origins of life concerns the physical and chemical processes that occurred soon after the Earth formed, 4 billion years ago. Scientists are trying to identify the reactions at the root of life that created the mud in which our primitive ancestors appeared. Integrating the environmental context into these equations enables us to define the properties of the geological formations and fundamental building blocks of life that shaped ecological niches at a specific moment in time.

At the time of planet formation, clouds of gases condensed into stars. Then, the surrounding dust collected into pebbles and clustered around them until, gradually, they became planets. Meteorites kept this ancestral form and bear witness to these early stages; their minerals and chemical signatures tell their story.
