Unformatted text preview: host selection locus (H) with each with new mutant alleles that shift survival and selection to the new host (e.g., apple from Hawthorn). Allochronic speciation was proposed as a model where species differentiated in time. Crickets of the genus Gryllus were taken as an example because species with virtually identical songs and morphology had evolved as spring adults versus fall adults (overwinter as juveniles or eggs, respectively). The model may apply but this particular example was shot down by phylogenetic analysis which showed that the two "allochronic species" ( Gryllus veletis and Gryllus pennsylvanicus are actually distantly related in the genus (see figures)....
