Amino acid racemization dating of fossil bones

When I’m talking with atheists or agnostics who are passionately against any and all religion, I sometimes find that they have inaccurate (or just plain wrong) ideas about the teachings of the Bible, the nature of the Christian faith and the qualities of the God I believe in.

A study of aspartic acid racemization in different fractions of 51 fossil bones of various ages, shows that the collagen-rich fractions do manifest increasing D-aspartic acid contents with increasing age.In turn, proteins are composed of folded strands of 20 different smaller subunits called "amino acids".All amino acids, except for one (glycine), come in two different forms known as the levoratory (L - left) and dextrorotary (D - right) forms.This means that the amino acid can have two different configurations, "D" or "L" which are mirror images of each other.With a few important exceptions, living organisms keep all their amino acids in the "L" configuration.
