Say, a pokemon is kept from evolving so that it can learn a move earlier. Let's say horsea with dragon pulse. will it's stats be lower than if it were to evolve into seardra and THEN learn the move at a later level.
No its states change equivalent to the pokemons species. I test that once and its states will go up accordingly to the evolved form like when a magikcarp evovels into a gyarados so your okay.
