The Human species (Homo sapiens) is a intelligent species that originated on planet Earth. As the Latin word for their homeworld is "Terra", Humans are sometimes referred to as Terrans. Occasionally "Terran" is used to distinguish Humans from the Mirror Universe.
Humans are a warm-blooded species with an average lifespan of around 120 years, although some individuals have achieved a much older age. Humans are bilaterally symmetrical bipeds who are descended from primates.
The Humans of Earth became warp-capable in 2063, which was the same year they experienced first contact with an alien species, the Vulcans. This is defining moment in Human History. All time before it was the Pre-Warp Epoch. All time after was the Post-Warp Epoch.
