Ancestor or Country Cousin
is a portion of a population after thirty-two
generations (AF). Clearly, nested-descent is
implied by the structure of the population. We
therefore hypothesize the existence of a
common ancestor and search for fossils of the
(most recent) common ancestor—or a close
relative of this ancestor.
the following image, the Nest of Letters
has been set to fossil- mode (ctrl-f).
Looking at the fossils we have available, the
closest match appears to be ".NWB.A..BT.."
(X2 in Blue) which shares features with all of
the current population including the
and the tenth-letter "T".
There is no way to determine from examining
the fossil itself if it is a direct descendent
of any of our population, however, we can see
that it is a probably close relative of the
(most recent) common ancestor.
Nest of Letters gives us the capability of
actually tracing the lines-of-descent. We
trace (ctrl-g) the ancestry of the
fossil (X2 in Blue), the genealogy of the
current population (AF) which starts
in Purple, and the population which starts
in Orange. We can see that the actual common
ancestor we were looking for is a missing
fossil (Y1 in Orange), and that our fossil (X2
in Blue) shares a common ancestor too (W1 in
Orange), but split off and dies out later on (AB in Blue).
