Weekly reading: Cladistic matrices, Wagner trees, and optimizations “by hand”

This week our weekly lab discussion group shifts gears from the empiricism/realism debate to actual, and mostly still “manual” (as if hands could think), character matrix assembly, Wagner tree construction, and upward-/downward-pass parsimony-based character state optimization. Consistency and retention indices. And WinClada and NONA. Let’s see how far the first session will take us towards understanding the interaction between characters, parsimony, optimizations, and trees.
