Recent advances in prebiotic chemistry suggest that hydrogen cyanide (HCN) serves as a fundamental precursor for nearly all essential biomolecules and protometabolic processes for life’s emergence.
Iron (Fe) is one of the most abundant elements in the solar system. It plays an important role in life by participating in redox reactions for energy generation (e.g., by […]
This chapter explores the key carbon compounds that shaped the Archean biogeochemical cycle, delineating their substantial impact on Earth’s primordial atmospheric and biospheric evolution.
Neoproterozoic snowball Earth events reflect globally frigid conditions thought to have stimulated changes in geochemical cycling with planetary biotic response. We investigated the impact of these events on sediment dynamics, […]
The atmosphere, the ocean and life on Earth interacted over the past 500-plus million years in ways that improved conditions for early organisms to thrive. Now, an interdisciplinary team of […]
Despite decades of research, there’s still much scholars don’t understand about life’s beginnings and early evolution. A UC Riverside paper has opened the door to understanding more and to framing […]
The dynamic nature of life’s ability to thrive in diverse and changing planetary environments suggests that habitability and survival depend on the evolutionary path and life adaptation to environmental conditions. […]
Scientists from the University of Copenhagen have made significant strides in understanding ancient ocean anoxia, with potential insights for today’s marine environments.
Research has uncovered important new insights into the evolution of oxygen, carbon, and other vital elements over the entire history of Earth – and it could help assess which other […]
Movement of rivers, mountains, oceans and sediment nutrients at the geological timescale are the central drivers of Earth’s biodiversity, new research published today in Nature has revealed.
