Adaptive radiation, a process in which many new species explode and occupy different ecological niches in a short time, can rapidly promote speciation and enrich species diversity. Genomic analyses have shown that phylogenies of closely related species often exhibit a high degree of reticulation, which is often associated with adaptive radiation.
