Evolution/Evolution families

An evolution family is a group of Pokémon who will all, if bred with or a Pokémon in the same Egg Group, make a Pokémon Egg that will hatch into the same Pokémon, excluding baby Pokémon. This also means that the most basic form has the potential to become any of the rest of the family, although it will ultimately be able to follow only one evolutionary path.

Stages of evolution
Pokémon can be divided into different evolutionary stages, based on where they appear in their evolution family. All Pokémon fall into one of four groups: baby Pokémon, unevolved Pokémon, first-evolution Pokémon, and second-evolution Pokémon. These groups are also the basis for the 's grouping of TCG Baby Pokémon, TCG Basic Pokémon, TCG Stage 1 Pokémon, and TCG Stage 2 Pokémon, respectively.

Due to the fact that no evolution family contains both a baby Pokémon and a second-evolution Pokémon, many regard baby Pokémon as the most basic form, while moving their evolved counterparts one level higher. For example, originally, was regarded as an unevolved Pokémon, however, with the release of  in Generation II, many now consider it to be more on par with Pokémon like, though its TCG classification remains the same.
