The mechanisms underlying the formation of species diversity have remained a subject of intense debate. In this study, we used Gryllidea (crickets) as a representative lineage and employed a phylogenetic comparative framework based on a robust phylogeny reconstructed from ultraconserved elements, mitochondrial genomes, nuclear ribosomal genes, DNA barcodes, and morphological traits. Our spatiotemporal evolutionary analyses indicate Gryllidea originated in the Early Jurassic, diverging into Grylloidea and Gryllotal…
