About this book
Provides references, approaches and points of discussion, and includes both conceptual and practical approaches to character coding. It covers the distinction between discrete and continuous data, molecular data and alignment and worked examples where character coding of morphologica data has been interpreted in the context of molecular phylogeny. Empirical examples of different coding strategies and their systematic repercussions, and a survey of what coding strategies are currently employed in cladistic studies are given.
