Implications of Moody et al. for the viability of terrestrial abiogenesis
Discover LifeRecent molecular reconstructions dramatically compress the temporal window available for the origin of life on Earth. Moody et al. (Nature, 2023) dated the Last Universal Common Ancestor (LUCA) to approximately 4.2 Ga—only ~300 Myr after the ...

Nitrogen heterocycles form peptide nucleic acid precursors in complex prebiotic mixtures
Scientific Reports, 2019 The ability to store information is believed to have been crucial for the origin and evolution of life; however, little is known about the genetic polymers relevant to abiogenesis.

The Origin of Life: A Philosophical Hypothesis in Dialogue with Modern Biology
ZygonCurrently, abiogenetic theories enjoy wide support when it comes to explaining the origin of life. Although the advances are undeniable, these models face significant difficulties, which, in our view, stem from the challenge of explaining the emergence ...

Life as a Cosmological Decoding Event: Reframing Abiogenesis
The origin of life remains a fundamental scientific enigma. Despite Earth's rapid emergence of life and its pervasive biosphere, laboratory experiments have consistently failed to replicate life's spontaneous transition from non-living matter. This paper

An Erdős-Inspired Perspective on Abiogenesis
Whether life is an inevitable consequence of the laws of nature or an exceptional outcome of prebiotic evolution is unresolved. Origin-of-life hypotheses primarily seek to reconstruct molecular pathways linking prebiotic chemistry to the first evolving ...

Prebiotic formation of thioesters via cyclic anhydrides as a key step in the emergence of metabolism
Scientific ReportsThioesters are high-energy derivatives of carboxylic acids that are essential in the functioning of today’s living cells. Their central role argues in favor of their early introduction in the abiotic reaction network which led to the emergence of life on
