Evolution is the process by which a Pokémon metamorphosizes, or evolves, into its next form. There are various ways a Pokémon can evolve, the most common of these being by level.Aside from changing the Pokémon's physical form, Evolution usually increases the Pokémon's base stats, and can alter its Types, Abilities, and even moves. However, Natures, EVs, and Shininess are preserved upon Evolution.
By definition, an evolution family is any group of Pokémon that are directly linked by Evolution. More clearly, the Basic or Baby Pokémon and all of its potential Evolutions are considered a single Evolution family. All eggs hatched from an evolutionary family will yield the same Pokémon.
Stages of EvolutionEdit
Not to be confused with a family with two stages, a Two-Evolution family is the most standard kind of Evolution. It is an Evolution family where the basic Pokémon evolves from its basic form twice. All starter Pokémon are members of Two-Evolution families. Some examples are Froakie, Dratini, Caterpie, and Lochro.
Not to be confused with Pokémon that do not evolve, a One-Evolution family is a family where the basic Pokémon evolves only once. It is disputable whether Fossil Pokémon can be considered part of the One-Evolution family, because the Fossil itself may be considered an Evolutionary Stage. Some examples of One-Evolution Families are Ratatta, Inkay, Larvesta, and Tazman.
Non-Evolving Pokémon are Pokémon that remain in their most basic form forever. All legendary Pokémon are Non-Evolving Pokémon.
Branch-Evolving Pokémon can evolve into multiple Pokémon, depending on its method of Evolution. Some examples are Poliwag, Eevee, and Ralts.
