No scientific work, to our knowledge, has ever hazarded a guess on what the mutation rate for autosomal CODIS-type markers might be. Is it like mitochondrial DNA, which has a molecular clock measured in the thousands or tens of thousands of years, or is it like STRs on the Y chromosome, with its much shorter timeframe? The question is important if you are trying to extrapolate the history of the human race from today's autosomal population statistics.
From what we can see, putting on diachronistic lenses, the mutation rates for the DYS values on what are commonly called CODIS markers or the DNA profile for individuals are very small. The values appear to have been set from the beginning of mankind and to have mutated little in the past 100,000 years.
If this is true -- and it cannot be a very big "if" or we would have more diversity between populations than what is known -- the oldest markers are Sub-Saharan African and the newest European. Statistical divides bear out this reading of the human genetic record, as shown now in our updated map included with the DNA Fingerprint Plus.
We will try to make some notes on the individual markers in future posts.
