Evolving Pokemon
Pokémon on Pokéheroes evolve when they reach a specific level. To find out what level a certain Pokemon evolves at, you should always use Bulbapedia or any other Pokémon encyclopedia.
This guide is about evolving Pokemon who need different requirements to evolve, and are different to the original games.
Item Evolution
To evolve a Pokémon with an Evolution Item, you will need to go to your Item Bag which can be accessed by hovering over 'Home'. You will then need to click the 'Evo. Stones' tab and then click "Use" next to the required Item. Then choose the right Pokémon from your Party/Storage Boxes and it will evolve (as long as the item fits for this Pokémon).
Happiness Evolution
To evolve a Pokémon that normally evolves with a high Happiness stat, you need to use the item "Soothe Bell". It's sometimes available at the Item Shop for 2000 
.
Or if your Trainerlevel is above 11 you can use the Salon to give your Pokémon an Acupuncture for 4000 to raise it's Happiness and evolve it after 15 minutes.
Move-Evolution
Since Pokémon can't learn any moves on PokéHeroes, the Pokémon that would normally evolve by learning a specific move have to be evolved differently on here. The Pokémon (e.g. Tangela) evolves when reaching the level on which it would learn this move in the original game series (for example Tangela at Lvl. 40). Exception: Piloswine evolves at Level 50 or higher.

Karrablast & Shelmet
As you may know, Karrablast and Shelmet would usually evolve by trading one for the other. However, it works slightly different on PokéHeroes. In order to make those two evolve, you have to trade one whilst the other is in the recipent's party (i.e trading a Karrablast to somebody who has Shelmet in their party).
