Human/The Galaxy

**Humans** (**homo sapien**), also referred as **Humanity** or **Mankind** was an race of bipedal beings from the now-destroyed planet Earth. Humans are the only sentient species to never gained contacted to the galactic communities of the Milky Way, with only Earth's sole survivor Samuel Colt having survived and gain contacted with the galactic community. Due to Earth's position being placed within the Unknown Region, no one outside of the Unknown Region knows of humanity, though the galactic Great War did cause Earth's untimely destruction.

As humans, they were the only extant members of the subtribe Hominina and—together with chimpanzees, gorillas, and orangutans—are part of the family Hominidae (the great apes, or hominids). Humans were terrestrial animals, characterized by their erect posture and bipedal locomotion; high manual dexterity and heavy tool use compared to other animals; open-ended and complex language use compared to other animal communications; larger, more complex brains than other primates; and highly advanced and organized societies.

## Biology and appearance

### Physiology

The Humans were a sentient species that belonged to the simians, a subgroup of the primate order of mammals.As such, they were similar to a number of other species variously designated as apes, including the sentient great ape, and a number of mammalian humanoids with a similar physiology. They were taxonomically referred to as *Homo sapiens*.

Humans were bipedal beings with a bilateral symmetry, having a front and a back end, as well as an upside and downside. Their body comprised a head, neck, torso, and four limbs. The upper limbs, called arms, ended in hands which had five fingers each; the lower ones, called legs, ended in feet with also five digits. The Human fingers had multiple points of articulation, and one of them was an opposable thumb that allowed for fine manipulation. Finally, they had one head perched atop a torso. Other sentient species that had a body type roughly similar to Humans and walked upright were often referred to as humanoids, since Humans were the most common example. Unlike other mammalian species such as Wookiees or Ewoks, they had only a light covering of body hair. Most of it was concentrated on the head and, in the case of adult males, face.

Humans were endotherms, or "warm-blooded" animals, meaning they maintained a constant body temperature independent of the environment using the energy from their food. While some mistakenly described themselves as carnivores,> Humans were in fact omnivores, subsisting on both animal tissue and plant-based foods. For that reason, their gastrointestinal system was much longer than that of true carnivores such as the Devaronians. Many Humans were partial to food products that were unhealthy for them because of their high fat or sugar content.

The Human genome was considered to be remarkably elastic. In reaction to environmental changes, selection pressures only needed few millennia to engage new genes and reshape the Human bodies. A consequence of that exceptional adaptability was the existence of many Near-Human species—that is offshoots of the baseline Humans who had followed their own evolution. Such offshoots included the the blue-skinned Chiss and the quarians.

As was common to many humanoid species, Humans had two sexes: male and female, with the latter being distinguished by their pronounced breasts, overall smaller stature and lesser quantity of body hair. With the study done on Samuel Colt, whether or not only Colt can accomplish this, is that study found due to their very elastic and adaptable genome DNA on Colt, he could be capable of interbreeding with other species such as the vulpera, quarian, lycanthrope, and even the cybernetic race of the protogens.
