Finding Common Ground

• TOL, BOL both mega-projects of practical value

• Sharing materials -- collecting, storage, access

• Coordinating informatics efforts -- standards

• Markers (reconciling uni- vs. multi-locus)

• Best practices, joint ethical code (one voice)

• Culture of science -- big vs. small science, credit

• Training/capacity-buildingYalePeabody Museum

Research Intersections/Opportunities

• TOL+BOL=DOL (Diversity of Life)

• Macro-micro intersection -- filling in the middle, “mesoscale” studies • Rates of evolution (phenotypic, molecular),

patterns of speciation, diversification • Models spanning levels -- clade, region, environ
