In so doing it is hoped that this book may provide an initial platform for future debates over the importance of this or that mechanism based on thorough knowledge of the available facts. The progression of the different chapters broadly follows a levels-of-analysis pattern, and all taxa (birds and mammals, including humans) are considered in each chapter, the only exceptions being Chapter 9, which specifically focuses on primates, and Chapter 6, which has a stronger human focus. 2 22 The comparative study of homosexual behaviour Any attempt to understand the behaviour of a complex organism such as a bird or a mammal is no easy task; trying to do so across dozens of species in a comparative perspective is rather more difficult, but not impossible.
