Left-Handed Amino Acids and Evolutionary Fact Twisting

People with a rudimentary understanding of biology should know that amino acids have both right- and left-handed forms. For amino acids to be useful, they must be intolerant: Amino acids are left-handed only, one right-handed protein wrecks the chain, so why don't you right-handed thingies try down the street at the nucleotide shop and see if they want your kind? The same-handedness rule makes the concept of even one DNA molecule arising by chance so tiny, it is impossible.

A press release from NASA regarding amino acids in a meteorite was treated with the usual enthusiasm by the evolutionist crowd. That is, the information was plugged into their preconceptions, praised as further evidence of evolution — but not carefully examined. Yet again, they embarrassed themselves.

A new suggestion of how life ended up with left-handed amino acids comes up short.
NASA Goddard press release reported that amino acids found in the Tagish Lake meteorite (British Columbia, 2000) showed some preference for left-handed aspartic acid, but less excess for alanine.  As usual, the science news media (e.g., Astrobiology Magazine, Science Daily, PhysOrg) and blogs (e.g., Darwiniana) all echoed the press release uncritically, graphics and all, so Creation-Evolution Headlines will have to do the job they should have done: evaluate the significance of the claim and see whether it solves the long-standing homochirality problem in biology (for background, see here and here).
