a . “Equally disappointing, we can induce copying of the original template only when we run our experiments with nucleotides having a right-handed configuration. All nucleotides synthesized biologically today are right-handed. Yet on the primitive earth, equal numbers of right- and left-handed nucleotides would have been present.” Leslie E. Orgel, “The Origin of Life on the Earth,” Scientific American, Vol. 271, October 1994, p. 82.
u “There is no explanation why cells use L [left-handed] amino acids to synthesize their proteins but D [right-handed] ribose or D-deoxyribose to synthesize their nucleotides or nucleic acids. In particular, the incorporation of even a single L-ribose or L-deoxyribose residue into a nucleic acid, if it should ever occur in the course of cellular syntheses, could seriously interfere with vital structure-function relationships. The well-known double helical DNA structure does not allow the presence of L-deoxyribose; the replication and transcription mechanisms generally require that any wrong sugar such as L-deoxyribose has to be eliminated, that is, the optical purity of the D-sugars units has to be 100%.” Dose, p. 352.
b . An important exception occurs in a component in cell membranes of eubacteria. There, the amino acids are right-handed. This has led many to conclude that they must have evolved separately from all other bacteria. Because evolving the first living cell is so improbable, having it happen twice, in effect, compounds the improbability. [See Adrian Barnett, “The Second Coming: Did Life Evolve on Earth More Than Once?” New Scientist, Vol. 157, 14 February 1998, p. 19.]
c . Recent discoveries have found that some amino acids, most notably aspartic acid, flip (at certain locations in certain proteins) from the normal left-handed form to the right-handed form. Flipping increases with age and correlates with disease, such as Alzheimer’s disease, cataracts, and arteriosclerosis. As one ages, flipping even accumulates in facial skin, but not other skin. [See Noriko Fujii, “D-Amino Acid in Elderly Tissues,” Biological and Pharmaceutical Bulletin, Vol. 28, September 2005, pp. 1585–1589.]
If life evolved, why did this destructive tendency to flip not destroy cells long before complete organisms evolved?
d . Many researchers have attempted to find plausible natural conditions under which [left-handed] L-amino acids would preferentially accumulate over their [right-handed] D-counterparts, but all such attempts have failed. Until this crucial problem is solved, no one can say that we have found a naturalistic explanation for the origin of life. Instead, these isomer preferences point to biochemical creation.” Kenyon, p. A-23.
u Evolutionists who work in this field are continually seeking a solution. Occasionally, someone claims that it has been solved, but only after checking the details does one find that the problem remains. In Germany, in 1994, a doctoral candidate, Guido Zadel, claimed he had solved the problem. Supposedly, a strong magnetic field will bias a reaction toward either the left-handed or right-handed form. Origin-of-life researchers were excited. Zadel’s doctorate was awarded. At least 20 groups then tried to duplicate his results, always unsuccessfully. Later, Zadel admitted that he had dishonestly manipulated his data. [See Daniel Clery and David Bradley, “Underhanded ‘Breakthrough’ Revealed,” Science, Vol. 265, 1 July 1994, p. 21.]
