This is not so renarkable as it may seem. Each of our genes is descended
from a single ancestor somewhere along the line. some (say, a gene for
cell division) go back a billion years, others (for hair) go back a
hundred million, some (for speech) maybe only 50,000. The mtDNA you
reference (200,000-800,000?) is the first effort to identify one of the
common-to-humanity genes. IMHO the eventual goal in this effort is to try
to identify the our most recent common ancestors. This would hopefully
identify the time and/or the birthplace of modern humanity.
