2021年4月21日 · Fast-forward to the 1920s when J.H.B.S. Haldane and A. Oparin offered an hypothesis about the life’s origins based on notions of the chemistry and physical conditions that might have existed on a prebiotic earth.

The prebiotic atmosphere is the second atmosphere present on Earth before today's biotic, oxygen-rich third atmosphere, and after the first atmosphere (which was mainly water vapor and simple hydrides) of Earth's formation.

2012年9月27日 · Whether in meteorites or on Earth, prebiotic chemistry may have occurred largely in an aqueous environment, as water is a ubiquitous component of the solar system and the Earth's surface.

1 天前 · A new study explores how complex chemical mixtures change under shifting environmental conditions, shedding light on the prebiotic processes that may have led to life. By exposing organic ...

Earth’s atmospheric composition at the time of the origin of life is not known, but it has often been suggested that chemical transformation of reactive species in the atmosphere was a significant source of prebiotic organic molecules.

2006年10月10日 · In this article, I will review proposed terrestrial sources of prebiotic organic molecules, such as Miller–Urey synthesis (including how they would depend on the oxidation state of the atmosphere) and hydrothermal vents and also input from space.

Microfossil evidence indicates that cellular life on Earth emerged during the Paleoarchean era be-tween 3.6 and 3.2 thousand million years ago (Gya) . But what is really what we call life? How, where, and when did life arise on our planet? These questions have remained most-fascinating over the last hundred years.

The goal of prebiotic chemistry is the depiction of molecular evolution events preceding the emergence of life on Earth or elsewhere in the cosmos. Plausible experimental models require geochemical scenarios and robust chemistry.

Our results suggest that the concomitant formation of poly-HCN microreactors and prebiotic organic molecules induced by silica would turn the waters of early Earth (and any Earth-like planets or moons) into an organic chemistry laboratory at the planetary scale.

2022年6月29日 · This book provides a broad but in-depth analysis of the latest discoveries in prebiotic chemsitry from the microscopic to the macroscopic scale; utilising experimental insight to provide a bottom up approach to plausibly explaining how life arose.
