I am involved in an analysis of some sequences, and it
is unclear if all of them really do share a history.
That is, some of them may not actually be part of the
same phylogenetic tree, and may represent independent
derivations of the same function.
I'd like to know what literature is out there that
deals with methods of testing to see if sequences
really share a phylogenetic history. What papers
are people aware of on this issue?
