Evolution: Difference between revisions

Evolution in Pokémon is closer to the real-life phenomenon of {{wp|metamorphosis}} rather than {{wp|evolution|actual evolution}}, as real-life evolution happens to populations over a long period of time, not to individuals. In the Pokémon Adventures manga, it is mentioned that Pokémon Evolution is an entirely separate phenomenon from the normal process of evolution, and is a mysterious ability exclusive to Pokémon that is still not fully understood. In [[Pokémon Super Mystery Dungeon]], it is described in the health class at the school in [[Serene Village]] as being akin to {{wp|puberty}}, where a Pokémon's body rapidly grows larger along with other changes that bring it closer to adulthood.

Real life evolution still appears to have happened in the Pokémon universe and is mentioned or referenced in multiple media. Different Pokémon lines are related to each other evolutionarily, but not necessarily all of them, as some are man-made or alien in origin. There is also [[Sinnoh myths#Sinnoh Folk Tales|Sinnoh Folk Story 3]] which claims there was a time there was no difference between Pokémon and humans. Many Pokémon can interbreed based on their [[Egg groups|egg group]] pointing to a potential relation. [[Pocket Monsters Encyclopedia]] describes how Pokémon adapt to different environments and uses [[Cinnabar Island]] and its unique ecosphere as an example which is thought to have strongly influenced its native Pokémon, like {{p|Growlithe}}, and now is famous as a home to many {{t|Fire}}-type Pokémon. Starting with the [[Generation VII]] games, each new region features new forms of previously known Pokémon called [[regional form]]s which look different, most of the time have different types, and sometimes evolve into different species.

* {{p|Gastrodon}} is relative of {{p|Shellder}} and {{p|Cloyster}}.

* {{p|Archen}} is believed to be a progenitor of bird Pokémon, although some of the latest research suggests this may not be the case.

* {{p|Tirtouga}} is reputed to be the ancestor of most turtle Pokémon, it lived in warm seas approximately 100 million years ago.
