Huh, didn't think I'd need to place it here, but the discovery of the Nidorina and Nidoqueen intentionally being unable to breed & yet their Pokedex entry mentioning their young made me wonder how that could work.
Eventually I made up a theory in Weird Theories that, honestly, has me convinced it's possible. I'll repost it here outside of a quote box to save you the trouble:
==================================================
So, I have weird new theory, maybe edging a bit on wishlisting or at least more going into an idea GF had but they didn't really follow-up on despite leading to a baffling decision they keep on today.
If you didn't know, FUN FACT, Nidorina & Nidoqueen can't breed. Very strange, especially since their male counterparts can. At first you could assume it was a glitch, yet its something which has been carried out with them for several gens and never "fixed".
If you haven't heard, an old Japanese Pokemon pre-release handbook guide was found recently and translated. The pre-release guide didn't really tell you much, but it did have Pokedex entries & trivia bits here and there that were never mentioned in the games. You can watch a video about it here (note it's a part 1 and the next part isn't out yet at the time of writing this):
Now, some of the information in the guide has likely been retconned, but there is one dex entry
which has caught the ears of fans: Nidorina & Nidoqueen being unable to breed was intentional. It wasn't a glitch that for some reason they were keeping, it was purposely done. Now a response to that video I did I was critical with the decision, noting how it doesn't make sense on both a mechanical level (Nidoran female are said to do all their breeding before they evolve, but the Nidorans evolve early at Level 16) and with newer dex entries (Nidorina's and Nidoqueen's dex entries keep mentioning their offspring despite being unable to breed). Now, I mentioned a "workaround" to these conundrums but in a mocking matter... but as I thought more about it, and thinking back to
another post I made where I had to read up on the behavior of hens (it had to do with the Chansey family and protection of their eggs), I think the workaround can honestly work if more thought was put into it. But that's not something for the Mystery & Conspiracy thread, well, it could fit there, BUT considering the topic matter I think it would fit better as a:
NEW THEORY: Nidoran F(emale) Breeding Behaviors
- So, first let's remember a Pokemon can choose not to evolve. Upon reaching level 16 a Nidoran F doesn't have to evolve, infact I could even see a Nidoran F trying to get itself up to at least Level 16 BEFORE it begins breeding. But for now, a Nidoran F is not evolving because, like all species, it wants to reproduce so its species can thrive and pass along its genes.
- And so, no matter how many levels it gains, a Nidoran F will stay as its basic stage until it finds a mate, most likely a Nidoran M(ale) or a Nidorino, and produce a clutch of eggs. That is when its maternal instincts kick in. Nidoran F are mentioned not to be fighters having short horns (but have a strong poison to use in self-defense), but Nidorina and Nidoqueen are noted to have thick armor scales. Thus, now having their clutch of eggs, Nidoran F has accomplished its goal of procreating so now chooses to evolve (which is easy enough to do as its over Level 16) to better protect its eggs and soon offspring. It has traded its biological function to develop new eggs in order to grow thicker armor to protect the eggs/offspring it now has.
- Now, this is where the Nidoran M/Nidorino comes in. As the Nidorina are tending to the Eggs, it's the males turn to start doing some leg work. Yes, as 1st stage evos they are perfectly capable of protecting their offspring, BUT they would do a much better job if they were a 2nd stage. So, the duty of the male counterparts is finding Moon Stones for both itself and its breeding partner, and hopefully they can do so before the eggs hatch to the baby Nidoran have a strong Nidoking and Nidoqueen parent caring and protecting them. In my original response I asked wouldn't it be strange for the partner for the Nidoran F to suddenly change, but then I realized it wouldn't be if BOTH partners underwent the same change.
So, is that all? No, because there are some additional questions that need addressing:
- Why can Nidorino and Nidoking still breed than? Likely a reflection of real like animals, notably mammals. A male's part in reproduction is just providing the sperm, in biological resource terms that's very little energy to do. Meanwhile its the female which has to spend the massive amount of resources to grow the child within them, and that's taxing on the body especially an older body. Female mammals go through menopause because the body has decided it likely won't (naturally) survive having a child. Now my above explanation danced around that, but I think that's the core idea behind this decision. Nidorino and Nidoking can still breed because it takes very little energy on their part to do so, could be possible for a sole Nidorino/Nidoking to have a harem. Now thinking of a Nidoking breeding with a Nidoran F is a bit squick, but this is the animal kingdom and if a Nidoking is strong than a Nidoran F would perfectly be happy making offspring with it (also who says the Nidokings need to breed with members of its own species; Kangaskhan need males so...). And after breeding that Nidoran F will evolve into the Nidorina, and if it has a Moon Stone become an equally sized Nidoqueen. In fact having an abundance of Moon Stones could also be something alpha male Nidokings use to attract mates as that not only shows its a provider but also means the female can be ready to protect its offspring to its fullest asap. Though, flipping this around, if we're to assume that the Nidoran family are more solitary creature and the males may not stick around/females may chase them off, then the male can just keep on doing its business and find another female.
- Is there any reason for wild Nidoran F to evolve before laying Eggs? I can see maybe in a colony structure there may be some Nidoran F who choose to evolve before laying Eggs. It would have to be a situation where there's not enough males (or not enough genetic diversity) that weaker Nidoran F decide it's better for its stronger sisters to pass on their genes, so they evolve immediately to provide extra protection for the colony (and especially their nieces and nephews to keep on passing down the family genes even if it's not directly theirs). Outside of that I would say the instinct to reproduce would be stronger for individuals living by themselves or in a small group that they would not evolve under normal circumstances.
- Why need a Moon Stone to evolve to their 2nd/final stage? In addition to the above explanation of being a way for the males to provide support and possibly use as a way to attract mates, could also be another way to show how much the Nidoran F's thinking & body has changed upon reproducing. It so much no longer sees a need to reproduce, it's perfectly willing to expose itself to radiation to further make itself stronger and bulkier to protect its offspring. While Nidorina may still have their reproductive organs but its shrunk and squashed by armor scales, Nidoqueen may have used the Moon Stone to completely remove them for extra muscle and armor. Heck, Nidoking could just be a byproduct of that, no reason to not give the males a 2nd/final stage as well.
