Origins of Chirality in Nature: A Reassessment of the Postulated Role of Bentonite
Abstract
Bondy and Harrington have proposed that selective binding of L isomers of amino acids and D isomers of sugars to bentonite is the mechanism by which the chirality of molecules in living cells was originally established. Further experiments indicate that the observations of Bondy and Harrington are better explained in terms of the effects of the binding to bentonite of the products of radiochemical decomposition.

Asymmetric adsorption and polymerization of amino acids reported with kaolinite and bentonite actually originated from experimental errors or contaminations.
“Asymmetric adsorption and polymerization of amino acids reported with kaolinite [266][267][268][269][270] and bentonite [271][272][273] in the 1970s-1980s actually originated from experimental errors or contaminations.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
