Human
From Bulbapedia, the community-driven Pokémon encyclopedia.
Humans are a species that live in the Pokémon world. They live in all regions, except Pokémon World (Mystery Dungeon). They have no known genetic relationship to Pokémon at the present time, but according to Sinnoh myths, they were originally a single species (possibly Mew) and were one and the same. Eventually, this species evolved (in the Darwinist sense) into humans and the various species of Pokémon seen today. At the present time, the species of Pokémon that are the most similar to humans is the Humanshape egg group.
