Preface to the Second Edition

Some kinds of problems may yield to sophisticated statistical technique; others will not. The goal of empirical research is—or should be—to increase our understanding of the phenomena, rather than displaying our mastery of technique. —Freedman [91] The first edition of APER was published five years ago. The subject of the book has grown in importance and audience during this time, so this second edition is certainly timely. Moreover, the changes in ape and several related packages have been so important in the last few years, that, for some time, I have felt this new edition was required. Though I acknowledge that the first edition of APER was quite appreciated by researchers, lecturers and students, it was not out of criticism. With this second edition, I have tried to improve on all possible points and issues as much as I was able to do. At the same time, I had to think over on the progress of the approach I presented five years ago. A difficult task was to review the development of the many new packages contributing to phylogenetics and evolutionary biology. It was my choice to focus on some of these packages with the aim to provide to the reader a consistent set of “techniques” to address a wide range of issues in phylogenetics and macroevolution. Even restricting our interest to these two fields, a number of packages are not considered in this book: this is a choice I fully assume. Besides, I decided to not tackle two related fields: population genetics and paleobiology. Both have seen critical developments in the form of several packages. A useful treatment of these would require two new books, so I have limited m
