I meant that those who developed the radioactive Carbon clock did not
calibrate it to the supposedly "broader context" of what was believed to
have been going on in the past --- although I bet some members of various
paleo______ fields warned them to do so in the early days. If we want a
scientifically sound, independent genetic mutations based clock it needs to
be discussed, analyzed, argued about on the physical aspects of the
clock(s), and in the case of the mutation clocks on the quality control of
the employed data sets as well.

The reason to have clocks based on physical principles independent of the
phenomena for which dating is desired, is to establish the dating outside of
the subject matter of interest, if for no other purpose than to suppress
in-grown or circular thinking about the subject matter.

I solicit all forms of argument about the clock model, but less interesting
are statements that basically say that some like or dislike, believe or
disbelieve, the clock ages for ydna tree nodes and clade MRCAs.
