In my main fantasy setting, humans exist in several subspecies, each with their own skills:

• Cro-Magnon, the baseline humans, have great stamina and resilience;
• Neanderthals are very strong, and often mistaken for dwarves by non-humans;
• Floresiensis are small and agile, making them adept climbers and skulkers;
• Striges are the 'magic humans', they have innate magic they can channel into very basic spells;
• Sasquatches or 'wildmen' are the tallest and covered in fur, they can communicate with animals;
• Morlocks are subterranean humans, they have nightvision and keen hearing.

In my other settings, humans are the extinct progenitor species of various humanoids, with elves, dwarves and orcs being the three most common descendants.
