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 …

[HTML][HTML] Origins of building blocks of life: A review
N Kitadai, S Maruyama - Geoscience Frontiers, 2018 - Elsevier
How and where did life on Earth originate? To date, various environments have been
proposed as plausible sites for the origin of life. However, discussions have focused on a …

Identifying the wide diversity of extraterrestrial purine and pyrimidine nucleobases in carbonaceous meteorites
The lack of pyrimidine diversity in meteorites remains a mystery since prebiotic chemical
models and laboratory experiments have predicted that these compounds can also be …

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 …

Origin of the RNA world: The fate of nucleobases in warm little ponds
Before the origin of simple cellular life, the building blocks of RNA (nucleotides) had to form
and polymerize in favorable environments on early Earth. At this time, meteorites and …
