The hot spring hypothesis for an origin of life
We present a testable hypothesis related to an origin of life on land in which fluctuating
volcanic hot spring pools play a central role. The hypothesis is based on experimental …

Protocells: Milestones and recent advances
The origin of life is still one of humankind's great mysteries. At the transition between
nonliving and living matter, protocells, initially featureless aggregates of abiotic matter, gain …

Challenges in evidencing the earliest traces of life
EJ Javaux - Nature, 2019 - nature.com
Earth has been habitable for 4.3 billion years, and the earliest rock record indicates the
presence of a microbial biosphere by at least 3.4 billion years ago—and disputably earlier …

Signatures of early microbial life from the Archean (4 to 2.5 Ga) eon
K Lepot - Earth-Science Reviews, 2020 - Elsevier
Abstract The Archean era (4 to 2.5 billion years ago, Ga) yielded rocks that include the
oldest conclusive traces of life as well as many controversial occurrences. Carbonaceous …

Covariation of hot spring geochemistry with microbial genomic diversity, function, and evolution
The geosphere and the microbial biosphere have co-evolved for~ 3.8 Ga, with many lines of
evidence suggesting a hydrothermal habitat for life's origin. However, the extent that …
