That's a keen observation and 
a good question about the number of differences in our mtDNA in relation to the 
CRS reference.

Let's start by saying that the CRS (Cambridge Reference 
Sequence) is just an arbitrary reference selected by some team of geneticist 
that were among the first to study the genetic sequences of mitochondrial 
DNA.  They decided to use the sequence of one of their subjects as a 
comparison reference, maybe one of their own samples, who knows?.  The 
selected mtDNA belongs to haplogroup H, the most prevalent haplogroup in 
Europe.  Therefore many Eur
