Weekly reading: Using dynamic homology without parsimony

Dynamic homologypart 1, part2, and now, for behavioral data (not exclusively, one presumes):

Japyassú, H.F. & F.d.A. Machado. 2010. Coding behavioural data for cladistic analysis: using dynamic homology without parsimony. Cladistics 26: 625-642. Available here.

More on this soon, well, hopefully. At least we are caught up now with our weekly reading posts.

Weekly reading: A dynamic homology approach for morphological data

Following up on last week’s wide-ranging explorations of dynamic homology sensu Wheeler, this week’s original, inspiring, and overall excellent paper by Martín Ramírez applies the issue to the challenge of properly (read: parsimoniously) assigning one or two of three potentially available sclerite ‘identities’ to their homologous positions in the complex male spider pedipalps and ranging over variously simultaneous inferred clades. Complex, engaging, and well conceived material for thought and possible application.

Weekly reading: Missing values, inapplicable states and polymorphic taxa

The third and likely penultimate session in our “explore cladistic coding” series. A brief primer below; more during our discussions and practices.
