The evolutionary radiation of a freshwater zooplankter with a mixed breeding system and a detailed, dated, subfossil record was examined. We sequenced specimens representing 10 out of 11 distinct morphospecies; these proposed species exhibited little or no sharing of mitochondrial haplotypes.
Moreover, the phylogenetic and haplotype networks revealed a radiation pattern that is concordant with the subfossil record-with an older Bosmina (E.) longispina radiating into several incipient species during the Holocene.
