Ummmm.... The bit about Eevees at the end is plain wrong. Things don't evolve due to their environment. It is merely that the creatures that have a favourable variation survive to produce offspring and pass on their genes, and so more things have the variation than don't. This is like junior high-level knowledge. DanJimi 10:25, 19 January 2008 (UTC)

Phione
I put Phione on the list of non evolving non legendaries, and it keeps getting removed. WHY???? It's not as though Phione is legendary. Missingno. Master 02:09, 27 December 2007 (UTC)
But it's not confirmed to be legendary. And IMO, the fact that one can recruit multiple Phione in MD2 PROVES conclusively that Phione is not a legendary (In the MD games, legendaries are strictly limited to one per game). -- Glitch and Official Pokémon. There is no real difference between the two. In my opinion, the two should be considered equal!-- quoted by Missingno. Master 15:20, 20 January 2008 (UTC)
If it isn't a legendary, why is it banned from the battle tower? It's definitely not because of it's battle prowess. No. It's because it's normally unavailable in normal play. You still need access to Manaphy to get them.
It's no legendary, but it's still an event Pokémon in a sense. - PDL
- The only Pokémon banned from the Battle Tower are legendary. Phione is legendary, albeit the crappiest of them. Plus, Missingno Master, you might wanna do something OTHER than just adding Phione in there, such as, oh, changing the count to 43 and making it so the table isn't f'd up.
- Plus, here's the thing: how much of a chance does Phione have of getting evolutionary relatives? ZERO! It has Manaphy. The other 42 have at least a chance of that.
- Jeez, I understand being the devil's advocate, but Phione just isn't worth it. It sucks in battle, sure, but so do many other legendaries. TTEchidna

Ahem. Phione is now officially not a legendary. 1 I take it this means I was justified in putting it back in the non-evolving non-legendary box thingy? -- Glitch Pokémon. Official Pokémon. There is no real difference between the two. In my opinion, the two should be considered equal!-- quoted by Missingno. Master 11:45, 5 February 2008 (UTC)
- Even if we assume that Phione is not legendary, which is unsubtantiated unless claimed or alluded to by the designers (that is, not any low-rank employee of an affiliated company), it still has no place on the list. The reason for this is that the list shows all Pokémon with some chance to evolve in later installments of the game. It has been observed, and in fact referenced in the Diamond and Pearl games, that legendaries need not evolve because they have reached their maximum potential as-is; therefore, there is no chance for any of the legendaries to evolve.
- It so happens that regardless of whether Phione is classified as legendary or not, there is no reason to believe that it will ever evolve. If it were to evolve, it would evolve into Manaphy, as any other scenario would be cumbersome (a legendary spawning a species not from its own family). However, the reason behind the fact that Phione does not evolve into Manaphy, which is that Manaphy is unique, will continue to hold beyond the current generation. -Unown Lord 14:07, 5 February 2008 (UTC)
- Missingno. Master, you do realize that link confirms that Phione is a Legendary, right? Gligar 15:27, 10 August 2008 (UTC)
- This conversation is from six months ago. Pokémon.com did list Phione as a non-legendary for a time, then changed it to a legendary status. ~$aturn¥oshi THE VOICES 15:41, 11 August 2008 (UTC)
Anime Evolution
In regards to the relation between the evolution in the anime than in the games. Wouldn't The anime be more reasonably sound than the games. Because I doubt that if Pokemon were real that most of these evolutions would occur exactly as in the games. The way I see it, the only reason why a certain Pokemon evolves the way it does in the game (with the exception of evolutionary stones and such) is to make it difficult for the player and it would be easier for a Pokemon Game developer if they limited it to one specific set of circumstances.
Granted there are a few exceptions: Such as evolutionary stones, and specific locations for a Pokemon to evolve, and perhaps it knowing a certain move. Though with Evolutionary stones, in an episode it said that the wind was able to carry evolutionary stones, so couldn't certain Pokemon evolve that way when it appears it just evolves naturally or mysteriously?
As for leveling up and trading, those just seem to make it more difficult for a trainer of the games to obtain Pokemon, that could easily be gotten by easier methods. --Dman dustin 13:51, 25 March 2008 (UTC)
new to community, first post
I'd like to add my finding in, I thought evolution however I'm not really sure how to add it in, and where it would go. I was trying to figure out if a pokémon whose evolution has been delayed would be as strong as the same pokémon of the same level and a "natural" evolution so what I did is I took a Pidgey and used rare candies to evolve it to 25 not allowing it to evolve until 27 the stats were as follows 71HP 39ATK 38DFNS 32SPATK 35SPDFNS 42Spd I then reset the game and gave the same pidgey rare candies this time allowing it the "natural" evolution at level 18 when it got to level 25 the stats were as follows 71HP 39ATK 38DFNS 32SPATK 35SPDFNS 42Spd
so we can infer that the level the pokémon evolves at does not affect the stats. If anyone wants to suggest a heading to put this in, or even shorten it up, by all means
About the comment at the page bottom
EVOLUTION IS NOT ABOUT CELL STRUCTURE. Eevee's evolution isn't akin AT ALL to real evolution. Evolution is triggered by Natural Selection, therefore, a single species cannot evolve. Only a population can. Just thought to make a side note. JirachiWishmaker0802 09:13, 13 December 2008 (UTC)
I agree, I'm a Biology student, evolution is about animals with favourable adaptations being statistically more likely to survive and so over many generations the favourable adaptations are spread throughout a population. Eevee's evolution is no way close enough to real evolution to get a mention, I will remove the sentence now... Prof. Pine 19:05, 24 April 2009 (UTC)
De-volution
Umm... Is it worth metioning in the article that only mentioned instances of "de-volution" is in Slowbro's pokedex entries. (When it loses its shellder) --Hyurnat4 21:28, 28 February 2010 (UTC)
- In the Pocket Monsters manga, It is also possible to De-volve as Isamu Akai's Clefairy evolved into a clefable and then back. Should this be added into the article as a subcategory, or as trivia? --Proctor 21:50, 15 July 2010 (UTC)
It's worth noting that some evolutions occur (or don't occur) if a pokemon's a certain gender.
- Combee only evolves if it's female
- Kirlia will only evolve into a Gallade if it's male
- and Snorunt into Frosslass when female.
I thought this would be in the article, but Combee wasn't mentioned at all. LordHeinz 00:37, 4 March 2010 (UTC)

Generation IV: Vulpix and Growlithe
Beginning with Generation IV, it is now possible to get a Level 1 Ninetales/Arcanine by hatching a Vulpix/Growlithe Egg received from breeding and evolving the newly hatched Vulpix/Growlithe with a Fire Stone, making Vulpix and Growlithe the first Pokémon that can evolve to their final stage of evolution at the lowest level ever. Unfortunately, the greatest trade-off of such an extremely premature evolution can be a poor move set which is very severe for Ninetales since it doesn't have any moves that it can learn by leveling up. --Arima 09:47, 26 May 2010 (UTC)
- This severe trade-off, however, can be alleviated to some degree through Move Tutoring and the use of TM/HMs. Therefore, it is merely a matter of choice between high stats and a reliable move set for either Pokémon. --Arima 10:06, 26 May 2010 (UTC)
- They aren't the first to do this. I can't remember for sure off the top of my head, but so can Togepi, Budew, and... yeah, it's early right now. Sorry. The Dark Fiddler - You enter a poorly lit room... 10:00, 26 May 2010 (UTC)
- Togepi and Budew do need to level up to evolve; however, it's true that many Pokémon can now evolve at Level 1. Staryu, Scyther, Onix, Porygon AND Porygon 2... basically any Pokémon which can both hatch from an egg and evolve without leveling up. So no, this isn't too notable. Although, come to think of it, perhaps Porygon ought to be mentioned, seeing as it's the only one to be able to evolve twice without leveling up. --AndyPKMN 11:29, 26 May 2010 (UTC)
- It's noted on Porygon-Z's and Roserade's pages that they are the only two Fully evolved three-stage Pokémon which can be legitimately obtained at level 1, and I think it might be noted on some of the others' pages that they can be legitimately obtained at level 1. Question is though, is it worth mentioning it here? Because it could be slightly irrelevant, as the ability to obtain them at level 1 isn't that much related to evolution. Werdnae (talk) 18:50, 26 May 2010 (UTC)
- Budew can't evolve at level 1 though, which is why Porygon's family is more notable. But, if we were to go with "fully evolved" instead of Porygon's family being able to evolve twice at level 1, then we could throw Budew's family in there. But I'm more in favor of Porygon only. R.A. Hunter Blade 20:34, 26 May 2010 (UTC)

Trivia
Each generation introduces a new method of evolution. Generation I introduces level-up, trading, and evolutionary stones. Generation II introduces level-up with high happiness and trading while holding an item. Generation III introduces level-up with high beauty condition. Generation IV introduces level-up while knowing a certain move, level-up while holding a certain item, and level-up in a certain location. Generation V introduces trading for a specific Pokémon. Should I add this to the trivia? Tk3141 22:02, 30 January 2012 (UTC)
Evolution by level at level 100.
As far as I know, an evolution by level is triggered by an actual level-up sequence, thus a level 100 unevolved pokemon can't evolve by level. I couldn't find a mention of this in the article. Is it accurate, and should it be either denied or confirmed by the article? PLA 10:00, 7 March 2012 (UTC)
- Yes, a level 100 Pokémon that evolves through level-up can't evolve. I don't think that this is important enough to mention though... but that's just my opinion. Dannyjenn 02:53, 20 March 2012 (UTC)
- It's implied in the Methods of evolution article, where it is stated that a Pokémon evolves due to three triggers, when being a level up. Obviously a Lv. 100 Pokémon cannot level up, so can't evolve if leveling up is their trigger. But I wouldn't know where to put it in this article. If the trigger is an evolutionary stone or a trade, then it still can. Samjohn95 23:35, 20 March 2012 (UTC)
Real-world evolution
"the existence of "extinct" Pokémon backs this up"
That's completely wrong. A species becoming extinct has nothing to do with evolution... it only has to do with evolving in the case that one species no longer exists because it became another species (like a mammoth evolving into an elephant). If it's just gone then that means nothing... dinosaurs are extinct and they didn't evolve into anything. Likewise, there's no evidence that the "extinct" Pokémon evolved into something else. They most likely just died out completely unchanged. Dannyjenn 03:18, 20 March 2012 (UTC)
Alternate forms of evolution
In Pokemon Snap, a Charmeleon evolves into Charizard if knocked into a vat of lava, and a Magikarp evolves into Gyarados if knocked into a waterfall. I believe these should be added. Jdrawer (talk) 02:06, 16 March 2013 (UTC)
- Those aren't really conditions. Ash's Charmeleon evolved just because it was angry at an Aerodactyl and wanted to beat it in a fight. Magikarp seem to be able to evolve whenever they feel threatened as well, such as when James kicked his into the ocean in frustration. Evolution conditions aren't limited to how they work in the main games. R.A. Hunter Blade 05:17, 16 March 2013 (UTC)
Halted Evolution - Bug? Safeguard?

Goodra
Should the method by which Sliggoo evolves into Goodra be mentioned as unique in the Methods section, or does that sort of count as a location-based evolution? -- EnosShayremtalk 06:08, 8 January 2014 (UTC)
- This method is unique, you level up Sliggoo to level 50 and if it's raining in the overworld, it will evolve into Goodra. Cinday123 (Talk) 07:05, 8 January 2014 (UTC)
- I understand the evolution method, what I was wondering is if it would be categorized as, technically, a location-based evolution since there's only overworld rain in certain areas. I'm just going to add it and it'll be removed if someone important doesn't like it there. -- EnosShayremtalk 08:06, 8 January 2014 (UTC)

Consistency

- Both Lycanroc are forms of the same Pokemon, as indicated by their having the same Pokedex number. Solgaleo and Lunala have different Pokedex numbers.

Prof. Elm's research

It would be good to explain why that figure doesn't match the automatically computed one included in the following sentence of the introduction. –Butterfreeism (talk) 02:17, 28 April 2020 (UTC)
Confusing information
Usually, I'd just edit the page myself, but I'm not really sure how to add up the percentages. At the top of the page, it states that Professor Elm's research (in which it's actually Rowan's not Elm's last i checked) states that 90% of all Pokemon are connected through Evolution, but the actual number is 81%, but the trivia section says 90% and 84%. Assuming 81 refers to all Pokemon that are not Legendary or Mythical, this is where the confusing information begins as it says 84 in the trivia. Is the 81 only referring to Pokémon as of Generation 4? I should make note that some dialogue in BDSP had altered text to DP, in reference to future titles that Sinnoh's Legendary Pokemon cannot evolve (not all Legendary Pokemon like in gen 4), meaning the 90% calculation stated earlier in the game is still accurate to some degree.

Pokémon Masters and Pokémon UNITE
Hi, I've been reading Bulbapedia for years, but I just created this account to point out there's no information about evolution in Pokémon Masters / Pokémon Masters EX in the spin-off section of this article. I'd do it myself but I don't have the eloquence nor the knowledge about writing that kind of content.
There's also the evolution that occurs in Pokémon UNITE. - unsigned comment from Omor (talk • contribs)
Porygon trivia out of date
Porygon isn't the only Pokémon that can evolve twice while remaining at level 1. Firstly, since it is possible to find level 1 Pokémon in Go, and Go doesn't require leveling up for any evolutions, any Pokémon found at level 1 in Go that can evolve twice can be evolved twice without leveling up. Of course, Go is a spin-off so it's not as interesting.
But even if we restrict ourselves to the main series, Porygon is still not alone. Because of the changes to evolution mechanics made in Legends Arceus, it is possible for a level 1 Pichu, Cleffa, Happiny, Togepi, and Budew to evolve twice without leveling up. Each of them evolve once by friendship and once via an evolutionary item (with Happiny being in the opposite order, but that doesn't affect anything).
And, yes, it is possible to gain friendship without gaining experience (and thus leveling up) in Legends Arceus. It's not very well documented, but after experimenting, I was able to confirm that using Potions to heal an injured Pokémon raises their friendship. Because of this, it is possible (though very tedious) to get the friendship up high enough to evolve without gaining XP, meaning friendship evolutions while remaining at level 1 are possible. I confirmed this myself with a level 1 Togepi, now a level 1 Togekiss, still with 0 experience points.--Gou (talk) 04:47, 14 June 2022 (UTC)
How, if at all, should Dawn's Piplup be brought up in the Anime section?
I feel like Dawn's Piplup bears mentioning here, because he, alongside Ash's Bulbasaur, are the only known instances in the anime of a Pokémon cancelling their own evolution while it is happening, and the differences between Bulbasaur's case and Piplup's case are interesting. Bulbasaur only needed to suppress their evolution once, apparently through sheer force of will with few adverse effects afterward, and was never shown needing to do so again, with no apparent outside influence preventing him from starting to evolve again. Piplup, on the other hand, was shown needing to suppress his evolution five times over the course of one episode and is heavily implied to have done so more times prior to the beginning of the episode, he needed to use Bide to stop his evolution in a process that usually left him winded at best or unconscious at worst (the only exception being in the middle of a battle), and only stopped needing to do so after he was given an Everstone. This seems to indicate that there are circumstantial factors in how cancelling evolution works in the anime. Red Knight (talk) 08:24, 30 January 2024 (UTC)
