The Pokéwalker is a useful tool in that it allows you to capture Pokémon while you're raising one of your Pokémon on the peripheral. Each area has half a dozen Pokémon within it. However, some of the Pokémon within it are only obtainable through the PokéWalker courses within the confines of HeartGold & SoulSilver and as such, so are their evolutions.
