Human

Despite the existence of various mutations (most notably, ghouls, super mutants, and trogs), normal humans, normals, or "smoothskins" are still the most common humanoid creatures on the planet. In the aftermath of the Great War, most of humanity began to mutate (albeit ever so slightly), and both the plots of Fallout and Fallout 2 make note of the changed nature of the humans living in the wastes. There are still "pure" (unmutated) humans living in the Wasteland, however, such as the Enclave. It is also reasonably possible that certain groups that have descended from Vault populations (Boomers, Vault City) have also survived, unchanged, having come out of their Vaults at a time where most radiation and fallout has subsided. That said, most people in the Fallout World can still be considered human, even though many of them have minor mutations, like additional toes, greenish skin, dwarfism or complete lack of hair. Still, they are nowhere near ghouls or Super Mutants. Varying degrees of cybernetics are also prevalent in the world of Fallout, though these are mostly present as perks and rarely is there any visible indication that cybernetics are present.

Known sub-species
Sub-species would be any group of humans that are different from normal humans but not as much as super mutants or ghouls. Known human sub-species created due to mutation/evolution over generations include: slags, swampfolk, trogs, psykers and beastlords. It can also be argued that cyborgs exist as a sub-species, though rarely in vast numbers. Cybernetics are visible in game as items, images, and perks/feats that can be earned through actions instead of level ups.

SPECIAL
In the SPECIAL character system, humans have 40 Character Points to divide between their Primary Statistics. Note that, in Fallout, Fallout 2, Fallout 3, and Fallout: New Vegas, the player can only play as a human character. Fallout Tactics allowed the player to control other races (see Fallout Tactics races), even though the player could only start as a human.

Fallout 3 and Fallout: New Vegas
Human NPCs suffer extra damage from headshots both in V.A.T.S., and in free fire mode. They prioritize their targets according to the weapons they carry. Any grenades the NPCs carry can be detonated with a well placed shot.

Shooting the enemy's weapons is a very effective way of disarming humanoids, as the weapons they carry are often of inferior quality requiring only a few shots, and their hand to hand damage is negligible. This does not apply to enemies using Unarmed weapons.
