Human

Humans (Scientific name Homo sapiens), "Inferior/simple-minded race" as seen by your generic super-intelligent and advanced race, "weak/frail race" as seen by your generic war-mongering race, and "Nom noms" as seen by the race that only exists to consume and grow) are a species of bilaterally symmetrical carbon-based creatures native to a small rocky planet orbiting Sol.   Humans have five appendages: the two longest ones underneath for locomotion, two more flexible appendages in the middle that split into very fine tentacles on the ends for manipulation, and a cranium up top for sensation. They stand upright and have nearly their entire cognitive organ contained within a bony shell inside the sensory limb, the rest of it in a bone sheathe in the middle "baggy" part. Humans on average stand erect between 1.5 and 2 meters in height, and mass between 50 and 100 kilograms.   Humans are descended from arboreal omnivores which migrated on the plains of a landmass in the Eastern hemisphere. They have gender dimorphism: females are smaller by 9% on average, only males have protrusions at the base of the locomotor limbs, and nearly all mature females have two protruding subdermal glands on their front thorax near the base of the manipulation limbs. A large sample of data from various competitions and world records based on gender have also shown human sexual dimorphism also extends to attributes of physical fitness. For example, males are slightly faster and considerably stronger than females, while females possess greater resistance to diseases. Both are particularly obsessed with mating.   Humans have an exceptionally high endurance, and their long distance running is unmatched by all but a few species. Some speculate early Humans hunted simply by stalking prey till it had to rest then bashing its head in, though the practicality of this is questioned. Human pain tolerance is high enough that they willingly ingest plants high in irritants that render them unpalatable to most species. Humans must consume a variety of acids every day to maintain health. Failure to do so results in weakness followed by death. Human blood is literally made of iron and capable of neutralizing acids if combined with them.
