• 2007
•Goal: To prototype a curated, ontology-based evolutionary phenotype database that maps to genetic databases
•Devo-evo synthesis; candidate gene discovery
• Enable data-mining and discovery for broad scale evolutionary patterns

User needs drove KB development:
•Search for candidate genes underlying evolutionary morphology
•Search for taxa with particular morphologies
•Aggregate morphological data across studies

Summary•Powerful queries not previously
possible for evolutionary phenotype data
•Meaningful integration with model organism phenotypic and genetic data
•Makes data accessible for broad group of researchers and creates opportunities for new and synthetic research
Semantic framework and reasoning tools provide:
Phenoscape as a resource
•Ontologies (anatomy, quality, taxon) + EQ data for any taxon
•Reasoning across EQ data types, uniting multiple studies, genes, etc.
•Your data?
