Our recent estimation of the divergence time and isolation of Death Valley pupfishes, including the iconic Devil’s Hole pupfish (DHP), rewrote widespread assumptions about this group. These species were previously assumed to be relic populations isolated over millions of years; our genomic analyses indicated recent colonization of Devil’s Hole within the past 105–830 years and frequent gene flow among Death Valley populations . These results understandably attracted substantial attention given the iconic battle for conservation and intense management of DHP ; nonetheless, a young age for this species should not diminish its conservation value. Indeed, we argue that the unique natural history of this species makes it a prime candidate for exhibiting one of the fastest mutation rates observed in any vertebrate .
