[Taxacom] Paraphyletic species

[Michael Heads]

Dear Ken et al.,
?
As?an animal example,?consider the?molecular phylogeny of?swifts, one of the?most difficult bird groups,?
?
Price, J.J., Johnson, K.P. & Clayton, D.H. (2004) The evolution of echolocation in swifts.?Journal of Avian Biology, 35, 135-143.
Price, J.J., Johnson, K.P., Bush, S.E. & Clayton, D.H. (2005) Phylogenetic relationships of the?Papuan Swiftlet Aerodramus papuensis and implications for the evolution of avian?echolocation. Ibis, 147, 79-796.

?
They took multiple samples (well, a few anyway) from each of a dozen species. One, Aerodamus vanikorensis, was shown to be paraphyletic, but the others were all OK.? Hats off to the 20th century bird taxonomists!?

Dear All,
? ? ???Following up on my response on Friday (to John Boggan's
question), I would suggest reading the paper cited below.? It would also
be relevant to Stephen's concern whether the term paraphyletic should be
applied to species (rather than just groups of species).? ? ? 
? ? ? The conclusion of the authors was that large numbers of plant
species are indeed paraphyletic.? I obviously agree with them.? Here is
the citation:? 
? ???Rieseberg and Brouillet, 1994.? Are many plant species
paraphyletic?? Taxon, 43:21-32.???
