Phylogenetic Comparative Methods and Approaches in Plant Science

Schenk, John [1].

Introductory remarks: The history of phylogenetic comparative methods and its future.

Following welcoming comments and an introduction to the symposium, I take a historical perspective on phylogenetic comparative methods.  I begin with a general account of comparative methods and argue that there have been three paradigm shifts: (1) characters are acquired by common descent; (2) characters are not independent because of common descent, necessitating that phylogeny be taken into account; and (3) evolutionary processes can be inferred with a model-based approach in a phylogenetic framework.  Following this historical perspective, I outline future directions that the field of phylogenetic comparative methods is moving towards, including constructing more realistic and complex models, improving statistical power, integrating fossil data, accounting for extinction, and constructing and testing informed hypotheses on more robust data.
