Abstract:Specialists in several branches of life sciences are trying to solve, piece by piece, the immensely complex puzzle of the origin of life. Some parts of the puzzle seem to appear with a rather high degree of clarity, while others remain totally obscure. We cannot be sure that life emerged only on our Earth, but we believe that the presence of large amounts of water in its liquid state is absolutely essential for the emergence and evolution of living matter. We can also assume that the latter exploits everywhere… Show more
“…A critical analysis of the terrestrial and extraterrestrial theories on the chirality of life 1,[4][5][6][7][8][9] has shown that, in all cases, various assumptions do not provide a key link in solving the challenge of homochirality, i.e., how to achieve a total shift in the chiral balance to obtain enantiopure biopolymers.…”
Chiral crystals remain one of the probable sources of first minute chiral symmetry breaking, a trigger that potentially caused an as yet unknown type of asymmetric autocatalysis during the formation...

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
