### May 3, 2019
* Ochoterena et al (2019) The search for common origin: homology revisited https://academic.oup.com/sysbio/advance-article/doi/10.1093/sysbio/syz013/5364027
* What is their goal for establishing homology? Phylogenetic inference, defining clades, which may lead to some disconnect with our own concerns.
* Discussion of levels of organization (ontogenetic, population , species) and their proposal that homology must be concordant among them.
* Discussion of relevance of the idea of paralogy to morphological traits
* what is the appropriate state space for phenotypes? we are trying to code phenotypes in that space of genetic/developmental networks but we will never be able to do so perfectly.
* does xenology preclude homology? doesn't seem like it needs to.
* how does it relate to ontological issues?
### Mar 1, 2019
* Tarasov et al. preprint:
* extracting presence/absence dependencies should be in place in time for workshop
* description of how algorithm works should be documented where?
* currently the algorithm is in OWL
### Feb 1, 2019
* Endara et al 2018 https://doi.org/10.3897/BDJ.6.e29232
* Some discussion questions (from Todd)
* Will this help reasoning escape from the implicit assumption of a normal and abnormal phenotype?
* How should position along a list be incorporated into semantic similarity?
* What would be the arguments for the open world form of the modifier ontology?
* Have we been misusing PATO, etc to serve as modifiers in the absence of these classes?
### Vogt 2018
Some interesting points (very rough notes from Todd):
* Paula makes the observation that the debate over the merits of atomizing anatomy into characters echoes a debate w/ "Berkeley school" of comparative morphology from her graduate days
* Would be interesting to see seeing whether use of a whole instance graph would lead to different max parsimony reconstructions than individual analysis of each ontologized character.
* In Vogt's approach, what a matrix would list as different characters could, in principle, be interdependent in Vogt's analysis (and hopefully reflective of integration in the organism)
* Might be able to test Vogt's idea with 'monograph to matrix', Andy Dean's wasp, or Laura J's fish dataset.
* Does Vogt's proposal really escape the assumptions of primary homology in phylo. analysis, or does annotation with common ontology terms mean the same thing in practice?
* Similarly, is the ontology taking on some of the burden of character state delimitation in Vogt's approach (as opposed to escaping the necessity of that step)
* Some interesting parallels between Tarasov preprint (from previous jclub) & Vogt
