In my original request I asked for feedback because I said I did not
understand the validity of calculating the TMRCA of P312* since it is
a paragroup rather than a clade.

[[ I'm just saying you can't allege there is an unusual problem or issue
with P312* TMRCA estimate simply because it is a paragroup.

It is a collection of haplotypes with a common ancestor --- some fellow with
the P312 snp but none of the other presently known snps downstream of P312
and any equivalents we presently have. There exists a tree for all the
paragroup members reaching back to that founder.

There must be some specific feature of the collection of P312* haplotypes
which leads to a possible problem --- not that it is a paragroup. And
whatever problem you come up with I can probably show examples of the same
problems happening for what are bonified clades. I'm not saying there may
not be problems in doing the TMRCA estimates.

In other words: next Halloween I am not going to go to the party wearing a
ydna "paragroup" mask --- it is not particularly scary. KN]]
