New Twist Found in the Story of Life’s Start (2014)

It proposes that life came from semiconducting crystals (various rocks and sediments in the ocean of hot primordial soup) affected by electrical discharges from ionosphere, and that right-hand chirality of isomers was influenced by Earth's magnetic field in Precambrea era.
That is...not true, or at least a little misleading. Each class of molecule in earth life twists the same way as other members of that class but not all classes twist the same. For example, nucleotides twist right/D, while amino acids twist left/L.
Scientists later discovered that this bias encompasses the entire living world. Synthetic chemical processes will generate both left- and right-handed molecules. But when nature makes a molecule, the product is either left- or right-handed. For example, all amino acids that are used to make proteins twist light to the left.
They found that in a racemic mixture, an excess of D or L amino acids results in longer, sturdier polymers that don't break down as readily when exposed to hazards such as hydrogen peroxide, and that amino acids delivered by meteorites were slightly biased towards being L and thus catalyzing longer D nucleotide sequences.
8. I can not ignore the possible relationship of the
inorganic and organic rhelms suggested by the transition of
cycloidal to helical motion, whether the vining of the
morning glory or the DNA helix. Could it be that evolution is
a function of the relative cycloidal curvature of space;
location in time on the brachistocrone, so to speak,
ie: that evolution is a sort of continuous creation?
9. It is tempting to suggest that the material world is the
rehlm of the curate cycloid from the limit of the common
cycloid to the limit of the circle. and that;
energy (waves) is the rehlm of the prolate cycloid from the
limit of the common cycloid to the limit of the line, and
that; the limit of the point/center/axis is the rehlm of the
V-oid and the black hole: and that;
the inorganic world of life is the rhelm of the helix.
