Antonie van Leeuwenhoek. Traditional religion attributed the origin of life to deities who created the natural world.

Miller is remembered for his work concerning the origin of life (and he was considered a pioneer of the topics of exobiology), the natural occurrence of clathrate hydrates, and general mechanisms of action of anaesthesia. He was elected to the US National Academy of Sciences in 1973. He was an Honorary Counselor of Spain's Higher Council for ...
While it is true that Miller-Urey setups produce racemic mixtures, [80] the origin of homochirality is a separate area in origin of life research. [ 81 ] Recent work demonstrates that magnetic mineral surfaces like magnetite can be templates for the enantioselective crystallization of chiral molecules, including RNA precursors , due to the ...
One ancient view of the origin of life, from Aristotle until the 19th century, is of spontaneous generation. [19] This theory held that "lower" animals such as insects were generated by decaying organic substances, and that life arose by chance. [20] [21] This was questioned from the 17th century, in works like Thomas Browne's Pseudodoxia ...

The PAH world hypothesis is a speculative hypothesis that proposes that polycyclic aromatic hydrocarbons (PAHs), known to be abundant in the universe, [1] [2] [3] including in comets, [4] and assumed to be abundant in the primordial soup of the early Earth, played a major role in the origin of life by mediating the synthesis of RNA molecules, leading into the RNA world.
