So, Why do some pokemon evolve into alola forms? The only one

>why are some humans Asian? It doesn't make sense!
You're retarded

It's explained for each. Rattata had to become nocturnal to avoid Yungoos. Meowth was bred by the royal family. Vulpix and Sandshrew lived in a cold area. Raichu... ate pancakes or something.

Anyway, the point is they actually do give explanations for them all.

I believe OP is asking why some Pokemon, line Cubone, evolve into their Alola forms.

OP here, I mean, Why does a regualr pikachu evolve into Raichu?
Exeggcute makes sense, But cubone, Pikachu...

*alolan raichu

>>28626712
apparently they are caused by a chemical reaction arising through the consumption of a moderate amount of a certain breakfast meal.

>>28626712
Mutations over time in the DNA, and being separated by the majority of their brethren.

>alolan forms are just a manner of allergic reaction to overconsumption

Some of the evolved forms are altered probably because only the evolved form experienced whatever hardship would lead to it needing to change. Cubone has a canonically explained reason, the Cubone children are protected by Marowak. Marowak needed to adapt to be able to protect them better. Cubone didn't need to adapt because it was being protected by Marowak

>but it evolves into needing to adapt just by getting older

Pokemon evolution is pure fantasy so you have to suspend your disbelief when justifying it in conjunction with more realistic evolution.

It could be the case that all Cubone in Alola have adapted: adapted into having the ability to becoming alolan Marowak. It's just not an adaption that changes them on the surface because it doesn't need to until they've evolved. This will be supported if, going forward, Cubone caught in Alola still evolve into Alolan Marowak when traded to other games.

This is literally what Darwin studied when he formed the basis for his theory of evolution.

Animals that are develop in contained ecosystems (namely islands) develop different traits than their mainland relatives.

Just look up the sea iguanas or really any island dwarfism/gigantism

Didn't mean to reply

On that note, others like Pikachu are a mystery. Raichu is one of the stranger alolan forms.

ITT: Why Darwinism is still for some reason a matter of debate.

>>28626961
The grains used in Alolan Pancakes have a mild psychotropic, addictive effect upon Pikachu causing the Pokemon's brain to grow cancerous tumors within it's brain.

Evolving them with the Thunder Stone cures the rodent by turning these tumors into a center of psychic power and giving Raichu an immunity to the once poisonous grain.

Alolan Cubones have been affected by Human traditions which have caused it over time to alter it's evolution; The Alolan (Read: Pacific Islander) performance of spinning burning staves whilst dancing and incredible reverence for their ancestors bleed through into actual changes within the Pokemon.

Actually is you take OP's idea this is more Lamarck

Because its a video game

Pokemon doesnt make sense anyways, why would different forms need to make sense?
