|Out of universe information|
Humans are a species (or race) that are prolific in several galaxies.
Humans originated in Celestis, a planet in a distant galaxy. Originally known as the Alterans,they split in two peoples, the Ancients and the Ori. The Ancients later seeded the Milky Way and Pegasus galaxies (probably more) with Humans, as both galaxies seemed to be devoid of sentient life. The Ori later created a new evolution of Humans that served as their worshipers. Humans were found to be good hosts for the parasitic Goa'uld who would take over control of the host's body. The Goa'uld spread humans across the Milky Way galaxy as they traveled. Human life forces are also the means of nourishment for the Wraith.

Humans come in two sexes; male and female. Like most other races, they reproduce sexually. Humans must rely on food and water periodically, or they'd die. Humans can live up to four or five days without water. (ATL: "Hide and Seek")
Human culture is one of the most (if not the most) diverse cultures in known universe.
Milky Way humansEdit
In the Milky Way galaxy, all humans originate from Earth, mostly brought to other planets by Goa'uld as hosts and slaves. Some of their descendants are still in the status of worshiping Goa'ulds as gods. Some other planets were abandoned and forsaken by their "gods" allowing inhabitants to live and evolve by themselves. Therefore, civilizations on these planets may become very advanced (such as Tollans) or, on the contrary, reproduce their culture through generations with little or no changes. Some planets are protected from Goa'uld by powerful races, for example the Asgard.
In the Pegasus galaxy, human life was seeded by the Ancients on an unknown number of planets. At the present time humans live on many planets under constant threat of Wraith cullings. Some of them worship the Ancients as gods, and a very select few have become Wraith worshipers. While some cultures passively wait in fear from one culling to another, some make attempts to break this vicious cycle, building shelters in an attempt to hide from cullings.
Others have found ways to fight the Wraith (like the Genii, the Satedans and Hoffans). The Travelers chose to completely abandon their home planet(s) and have been able to avoid any contact with Wraith by creating generational ships and living in space for generations.

Alteran Home Galaxy humansEdit
In the Alteran Home Galaxy, human life was seeded by the Ori on an unknown number of planets after their ascended. These humans became the Alteran people, and eventually abandoned their galaxy in an effort to spread their religion of 'Origin'.
Unnamed galaxy humansEdit
In an unnamed galaxy, where human life descended from the descendants of an alternative Destiny expedition. The people have scattered around the galaxy to several dozen planets and founded off-world colonies. (SGU: "Common Descent", "Epilogue", "Blockade")
Some civilizations possess heritage from the Ancients. Sometimes on these planets, the ability to control Ancient technology makes a human the rightful ruler in the eyes of fellow citizens. (ATL: "The Tower", "Harmony")
Further along the line of Human evolution, into Near ascension, provides a number of unique abilities such as telekinesis, telepathy and similar such talents. Some Ancient technology can also give humans this ability. (SG1: "Metamorphosis") (ATL: "Tao of Rodney")
A person that makes use of 68% of their brain at any one time can make use of these advanced abilities (more become available as one evolves further.) A human that reaches 90% is even capable of willfully reaching Ascension. (SG1: "Prototype")
Species descended from Humanity/AncientsEdit
Species, probably, evolved separately from Ancients or Earth's humanity, but in similar ecological conditions. As a result, these species are more or less human races, but with some physiological differences.
