To establish analytical frameworks for comparing rates of molecular evolution and determining whether host and parasite lineages split synchronously during cospeciation.
Analyzed phylogenetic tree concordance and molecular clock models across interacting host-parasite clades.
Evaluated theoretical approaches that integrate lineage branching orders with estimates of absolute or relative divergence timing.
Demonstrated that congruent phylogenetic tree topologies alone do not prove co-divergence without evidence of simultaneous timing.
Showed that comparing relative rates of molecular evolution enables researchers to distinguish true synchronous cospeciation from independent host-switching events.
