Since some people are too lazy to look under "Evolve Starter" or just want to know what evolves to what and how, I took some time quite awhile back and noted down all the evolutions to every pokemon and the method.  Just hit Ctrl+ F, enter the name of the pokemon and bingo.  Note:  For Shiny/Dark pokemon, multiply the evolution level by 2 and for Golden pokemon, multiply by 5.  Another note:  Evolving does not affect a pokemon's gender or Shiny/Dark/Golden status.
