INTRODUCTION Carbonaceous chondrite meteorites are among the most pristine extraterrestrial materials available to date for study. They underwent aqueous alteration below 150°C, which made them rich in hydrated phyllosilicates (Brearley, 2006). CM chondrites are considered to have undergone various degrees of aqueous alteration, making them abundant in phyllosilicates.

Seventy years ago, Stanley L. Miller described the synthesis of amino acids from a simple mixture of gases, spurring investigations into the chemical origins of life. Here we discuss the rise, fall and renaissance of endogenous amino acid production. Refers to Miller, S. L. A production of amino acids under possible primitive Earth conditions. Science 117, 528–529 (1953).
