Para este mes de Octubre de 2009, propongo tomar como "nuestro personaje del mes" a Joseph Felsenstein, cuyo nombre suena fuerte junto con quienes han contribuido en el estudio y análisis filogenéticos, así como la producción de software para análisis filogenético.
A continuación les pongo una pequeña biografía tomada de Wikipedia (y no es chafear) sobre su vida y estudios.
Tomado de Wikipedia: Joseph Felsenstein
Joseph "Joe" Felsenstein is Professor in the Departments of Genome Sciences and Biology and Adjunct Professor in the Departments of Computer Science and Statistics at the University of Washington in Seattle. He is best known for his work on phylogenetic inference, and is the author of Inferring Phylogenies, and principal author and distributor of the package of phylogenetic inference programs called PHYLIP. Closely related to his work on phylogenetic inference is his introduction of methods for making statistically independent comparisons using phylogenies (Felsenstein, 1985).
Felsenstein did his undergraduate work at the University of Wisconsin–Madison where he did undergraduate research under James F. Crow[1]. He then did doctoral work under Richard Lewontin in the 1960s, when he was at the University of Chicago[2], and did a postdoc at the Institute of Animal Genetics in Edinburgh[2] prior to becoming faculty at the University of Washington.
In addition to his work in phylogenetics, he is also noted for his work in theoretical population genetics, including studies on selection, migration, linkage, speciation, and the coalescent.
Honors include membership in the United States National Academy of Sciences and receiving the Darwin-Wallace Medal in 2008 (given every 50 years by the Linnean Society of London).
Y por si fuera poco les dejo un pequeño historial de publicaciones hechas por Joe, que sin lugar a dudas son tan complicadas como interesantes.

y la rola?
Bueno, leyendo un poco más sobre la canción del amphioxus que te dije, descubri que Felsenstein no la escribió, sino que la escuchó cuando estudiaba la universidad, pero la canción se remonta a 1920, algo ya viejita, además no me pareció un súper tema de discusión, ya que la mayoría de los miembros del apolab estudiaron otra carrera ajena a la zoología y poco conocen de este organismo tan pequeño y simple.
Felsenstein se ha dedicado también a probrar hipótesis y tratar de resolver problemas con cuestiones asociadas al uso de los métodos de reconstrucción filogenética presentes a la fecha, tanto aquello que usan distancias (como NJ, UPGMA) como los que usan métodos de optimización (Parsimonia, Maxima Verosimilitud [ML]), así como optimizar algoritmos e implementarlos en software (por cierto de libre distribución) para su utilización.
