From Hybrid To Species

I would think that if the hybrid was reproductively isolated from the parental species, then it would be considered a species. Despite the debate regarding the utility of the biological species concept, it is the default concept that is applied to these instances of hybrid speciation.After reading an article in A/C I began wondering... what does it take for a hybrid to be considered a species?

Obviously the species concept is artificial.

Allow me to disagree. Species is the one taxonomic category that exists in nature. Everything above that is a human construct. No one "species concept" fits all the variations in nature. P. formosa is an odd case, but they have their own genome even if behaviorally they need to interact with one of their ancestral species. It's like the parthenogenic whiptail lizard species, which have higher reproductive output if they're mounted by other members of their all-female species before producing eggs through meiosis. Often we need to step out of our mammalian view of the world.Obviously the species concept is artificial.
