Summary

The lecture by Carlos Briones at Fundación Orotava presents a comprehensive overview of prebiotic chemistry and the RNA world hypothesis as key frameworks for understanding the origin of life. Briones begins by situating the question within astrobiology and the universe, referencing images from telescopes. He outlines two methodological approaches: bottom-up (from chemistry to biology) and top-down (from present biodiversity to LUCA). He then discusses foundational experiments: Miller-Urey’s synthesis of amino acids, Joan Oró’s synthesis of adenine, and the Murchison meteorite analysis supporting extraterrestrial organic chemistry. The lecture emphasizes the RNA world hypothesis, where RNA serves as both genotype and phenotype, enabling evolution. Briones also discusses the necessity of combining replication, metabolism, and compartmentalization for life’s emergence, and highlights various definitions of life, including Joyce’s operational definition and Margulis’s poetic description. The talk concludes with reflections on whether life is a product of chance or necessity, and the importance of interdisciplinary cooperation in this research.
