Hi all
I receive the mailing list of phylogeny and morphometric geometry and I post the same message to both lists. This is about doing phylogeny with morphometric geometry, a subject that could bring an anathema on me because 1) quantitative data are generally considered to be unsuitable for doing phylogeny, especially with a cladistic method, 2) among quantitative data, morphometric ones are considred to be one of the worst. Although I understand and agree for the second reason, I never really understood why cladistic could not be performed with quantitative data. I understand that there are technical reasons but I think there are other historical reasons such as the long war between phenetic and cladistic, that still bring a doubt on studies doing phylogeny with quantitative data. Let's come to the point, I recently discovered 2 articles that, to my opinion, threw a stone in the pond as we say in French: 1. Phylogenetic morphometrics (I): the use of landmark data in a phylogenetic framework. Santiago A. Catalano, Pablo A. Goloboff, Norberto P. Giannini, Cladistics, <http://onlinelibrary.wiley.com/doi/10.1111/cla.2010.26.issue-5/issuetoc> Volume 26, Issue 5, pages 539549, October 2010 2. Phylogenetic morphometrics (II): algorithms for landmark optimization. Santiago A. Catalano, Pablo A. Goloboff, Norberto P. Giannini, Cladistics Article first published online: 28 JUN 2010 DOI: 10.1111/j.1096-0031.2010.00318.x Since several years I try to use my morphometric data in a phylogeny perspective. I used several methods, including the maximum likelyhood method with Philips software of Mister Felsentein and the cladistic method of TNT software of Mister Goloboff, one of the author of the 2 papers. I just wanted to express my opinion about this matter and I think those 2 papers will bring the pylogeny perspective in a new paradigm. Thanks for reading my note until this point!
