Looking for the origin of life in cosmochemistry: Asteroids and their carbon-rich meteorites

Sandra Pizzarello

Abstract


Carbonaceous chondrite meteorites are carbon-containing fragments of primitive asteroids that have offered the only samples available to date giving insights into chemical evolution in laboratory analyses. Their study has revealed that abundant organic chemistry came to be in the Solar System ahead of terrestrial life and, by the input of these meteorites and comets, might have aided in the origin of our planet’s biochemistry.

Keywords


Biogenic elements; carbonaceous meteorites; chemical evolution; chirality; chembiogenesis
