so you want to shoe a horse

Phylogenetic reconstructions using a combination of nuclear and mitochondrial DNA sequences calibrated with fossils to estimate ages of divergences suggests that the genus Lepomis diverged from the black bass in genus Micropterus, its sister taxon, about 25 million years ago. The deepest split among currently living species of Lepomis is dated to ~15 million years ago and separates genus Lepomis into two clades: clade I that leads to the modern bluegill, orange-spotted, green, and warmouth sunfish, and a clade II that includes the modern long-ear, red-breasted, pumpkinseed, redear, and red-spotted sunfish. The timing of this speciation event roughly corresponds with the Middle Miocene disruption that resulted in increased aridity on the plains of North America and a transition from savannah to grasslands, although the relevance of these environmental changes to the evolution of Lepomis is unclear.
