Pokémon GO evolution chains

Like most Pokémon games, Pokémon GO allows Pokémon to evolve. However, rather than evolving by levelling up (or powering up as it's named in GO), evolution is achieved by collecting special Candy for each Pokémon.

Catching a Pokémon yields Candy named for the base form of that Pokémon - i.e. Bulbasaur Candy is awarded for catching a Bulbasaur, Ivysaur or Venusaur. First stage catches (e.g. Bulbasaur, Geodude) yield 3 Candy; second stages (e.g. Ivysaur, Golduck) yield 5 Candy; and third stages (e.g. Venusaur, Gengar) yield 10 Candy. Transferring a Pokémon to Professor Willow gives an extra 1 Candy. Hatching Pokémon from eggs yields higher Candy amounts.

Below are the evolution charts for all Pokémon currently in the game data along with the amount of Candy required. (Pokémon not yet available are listed here at the bottom.) Some evolutions require items or special conditions; these are all noted where relevant.
