Terran (Species)

The Terran or Humans (Homo sapiens) were one of two known spacefaring intelligent species to have originated from the planet Earth. As the Latin word for their homeworld was "Terra", Humans were sometimes referred to as "Terrans". (This usage was consistent in the mirror universe.) Occasionally the term Terran was used to distinguish Humans living on Earth from those resident on colonies on other planets and moons. Some people used the adjective "Terran" to refer to subjects or institutions associated with Humanity (Terran cuisine, Terran literature, Terran art, etc.).

==Physical Appearance==
Bilaterally symmetrical bipedal primates, Humans were a warm-blooded humanoid species with an average lifespan of around 120 years, although some individuals achieved a much older age. They had two hands and two feet, each of which had five digits.
They had evolved from the australopithecines. At least three sentient species of Humans existed on Earth: Homo sapiens, Homo floresiensis, and Homo neanderthalensis (the Neanderthals). These species coexisted for some time until first the Neanderthals became extinct, followed by Homo floresiensis, leaving only one species of Human in the present. Humanity's closest living relative was the chimpanzee.
The Human species was one of the more distinct sentient groups present in the Milky Way Galaxy as, while they did not possess any dominant or noticeable bony ridges around their face or on their bodies as was common to many races throughout space, they did possess a great deal of phenotypic diversity within their species. Skin color, eye color, blood type, facial structures, hair color, and hair type varied considerably between individuals and made nearly every single Human distinct in appearance from the next. An exception to this was in the case of identical twins, an anomaly that occurs in approximately three in every 1,000 Human births.
They had two sexes, as was common to many humanoid species. The female of the species was fertile once a month after she reached puberty (between the age of twelve and sixteen) until the onset of a biochemical stage known as menopause (between the age of 45 and 55). Human gestation lasted nine months. The make-up of Human DNA structure was significant, as, with some modifications, it allowed them to crossbreed successfully with a wide range of other races across the galaxy, including Vulcans, Klingons, and Betazoids.
