Fwd: Re: More on the 'cladistics' of sequences

[Jim Whitfield]

Two other quite influential ones that could be mentioned in the
context of whether (or how)
a priori polarization of characters is required are:

Maddison, W. P., M. J. Donoghue and D. R. Maddison. 1984.  Outgroup
analysis and parsimony.
Syst. Zool. 33: 83-103.

Meacham, C. A.  1984.  The role of hypthesized direction of
characters in the estimation of evolutionary history.  Taxon 33:
26-38.

These two discuss methods more like the way modern parsimony programs
work, especially with multiple outgroups.

                                                Cheers, Jim
