The field of phylogenetic reconstruction has seen tremendous advances in the last few decades. The sources for those advances have come from different subdisciplines of biology (evolution, genetics, or molecular biology) and even outside biology (computer science, mathematics, philosophy). But a number of the contributions to phylogenetic methodology have come from workers interested mostly in systematics and taxonomy. Systematists were instrumental in establishing phylogenetics as an important field in the late 60s and early 70s. The general outlook of researchers in systematics and taxonomy, and the kinds of problems they are interested in, tend to differ from those of people approaching phylogenetics from evolutionary biology or computer science. Systematists focus more on the relationships between species, are more interested in diversity than in model organisms, and tend to rely much more heavily on morphological characters—which are used as part of standard taxonomy. More evolutionarily oriented phylogeneticists, instead, tend to focus on the use of trees for testing specific hypotheses. Both are different kinds of problems and legitimate fields of inquiry; personal preferences lead to focusing on one or the other type of problem. As someone with an upbringing rooted in systematics and taxonomy, I felt that no recent book summarized the main advances in this field from this perspective. This is the first reason to write this book.
