people have a hard time wrapping their heads around the years of hardwired "science" People still believe the hybridization does not occur in the wild, a specie will always remain as such until millions of years go by. Matter of fact, stingrays are being hybridized daily, and offsprings are mostly all viable. and there is scientific literature that most of the parachromis sp. larger guapote hybrdize with good frequencies. Maybe genetically they're not so seperated to begin with. How do we know that that's not how new species are being discovered or rather produced in the wild, for adaptation and survival. As species become extinct as we so fear for, new ones are coming along.
