Glossary Codiversification: speciation events in one lineage of species (e.g., plants) are correlated with speciation events in a second lineage of species (e.g., insect pollinators). Coevolution: reciprocal natural selection that causes reciprocal evolutionary changes in the traits of two or more interacting species. Cophylogeny: the degree to which two or more lineages share a similar phylogenetic topology. Cospeciation: the matching of speciation events in two or more interacting taxa.

Geographic mosaic: differences in coevolved phenotypes or the degree of coevolution among populations within a coevolving species. Phylogenetic tracking: a pattern in which speciation events in one lineage mirror speciation events in another lineage. Usually assumed that one lineage speciates first and is followed by speciation in the other. Reciprocal transplant experiment: a method in which individuals are swapped among partner taxa and their fitness from interacting with their local and foreign partners is compared. Speciation-extinction estimates: estimates of the speciation and extinction rates for a lineage that are usually derived from comparative phylogenetic analyses. The two rates together determine the net diversification of a lineage.
