Florida man and Balkan uncle are surprisingly unrelated to each other in any direct way and are instead examples of convergent evolution wherein similar pressures can create similar ecological adaptations which under the right circumstances result in similar aesthetics. Similarly the Pan American Redneck (Which Florida man is a sub species therein) actually represent merged hybrid populations derived from distinct but ancestorally related populations resulting in the Appalachian, Ozark, and California Rednecks. Though it should be noted that Redneck analogues populations are more than capable of interacting without issue as seen with Australians and California Rednecks or when Appalachian Rednecks interacted with Bosnians during the Bosnian war.
