The chirality of life, an issue I’ve discussed on numerous occasions in these and other pages, emerges as yet another source of pseudo-science for the intelligent design lobby. Apparently, the bias in handedness among the molecules of life – amino acids, DNA, etc, could not have arisen spontaneously without a guiding hand…
An interesting discussion on this very subject is underway at The Panda’s Thumb blog, it will be interesting to see where it leads. However, my own interviews with chemists on this subject over the years point to a wide range of natural phenomena that could have led to the emergence of the chiral bias with no need to invoke a supernatural hand.
