Humans (Homo sapiens), also known as Terrans, were a warp capable humanoid species from the Alpha Quadrant. The species originated from the planet Earth in the Sol system. Humans were the only surviving race of several sentient/intelligent species to have evolved from the Genus Homo. Humans were also one of two known space-faring intelligent species to have originated from Earth; the other being the Voth, who had come to live in the Delta Quadrant by the 24th century.
As the Latin word for their homeworld was "Terra", Humans were sometimes referred to as "Terrans", but not always. (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.). The Borg designation for Humans was Species 5618.

A founding member of the United Federation of Planets, Humans of Earth became warp-capable in 2063, which was the same year they experienced first official contact with an alien species, the Vulcans. The first warp-drive was engaged on April 5th of that year by Zefram Cochrane.
By the 24th century, Human society had changed from what it was for most of recorded history. On Earth, hunger, war, disease, famine, and poverty had largely been eliminated. The acquisition of wealth was no longer the primary driving force in the lives of many Humans. A great deal of emphasis was placed on the importance of continued social and personal development. Thanks to the non-currency based New World Economy and the development of replicators, material needs were largely satisfied. Although money was no longer used by Humans within the Federation, they did use gold-pressed latinum and other forms of currency (such as Bajoran litas and credits) in places where it was still needed, such as Quark's. The idea behind not using money was that rather than seeking material possessions, Humans worked to better themselves and the rest of Humanity (see Human philosophy). It must be noted that all of this more specifically applied to Humans within the Sol system, as many Earth colonies were known to have developed vast cultural differences from other Humans and some had even fallen into chaos, most notably Turkana IV.
In the past, Humans were often driven by such things as money and power, but they managed to overcome their need for materialism, and began working to better themselves, and pursuing exploration and research.
Humans were well known throughout the galaxy for their high adaptability to many climates, as well as their physical endurance.
Their lifespan ranged from 110 to 130 years, depending on the individual.
Human spacecraft ranged from civilian freighters to starbases, and from shuttles to giant exploration cruisers.
These colonies were established by various Earth governments or United Earth and largely remained in close contact and dependence with and on Earth. Most of them were older than the United Federation of Planets itself.
