Humanity

 ![Humanity](wiki-images/e7/e730ecdabb443351d57db9e1bd229fa2.png)   **Humanity**, also known as **Mankind**, is a sapient species originating from the planet Earth. It is currently the only extant spacefaring species in the galaxy, with all others having either died out, disappeared, or regressed to a pre-spaceflight state.   ## Biology   Since taking to the stars, Humans have developed multiple ways to edit their own genome to adapt to alien worlds. This means that while they still count as the same species, they might have radically different genes. This section uses Pre-Spaceflight humans as reference for biological information.   *   **Classification**: Terrestrial mammals. *   **Locomotion**: Bipedal, with 4 limbs. *   **Respiration**: Breathe oxygen and exhale Carbon dioxide. *   **Compatibility**: Biologically compatible with a wide array of alien lifeforms, enabling humanity to digest alien food and contract alien diseases.   > **Note**: The moon Proteus is deadly to an unmodified human due to its environment.   ## History   ### Pre-Spaceflight+Humans originated on the planet Earth, evolving from tree-dwelling primates on the continent of Africa. Due to their advanced intelligence, they spread and adapted to virtually every part of the planet.  -Humans originated on the planet Earth. They evolved from tree-dwelling primates on the continent of Africa and, due to their advanced intelligence, spread and adapted to virtually every part of the planet, with only a few exceptions.+Around the 13th century AD, Earth was visited by the alien species known as the [Architects](https://wiki.subnautica.com/sn2/Architects). This is the earliest known interaction between humanity and extraterrestrial life. Knowledge of this encounter comes indirectly from the Architects, who carried a human sword with them when they left Earth. It was later discovered on a distant planet and analyzed by Ryley Robinson, revealing its origin.  -Around the 13th century AD, Earth and its human inhabitants were visited by the alien species known as the [Architects](https://wiki.subnautica.com/sn2/Architects). This is the earliest known interaction between humanity and extraterrestrial life. Knowledge of this encounter comes indirectly from the Architects, who carried a [human sword](https://subnautica.fandom.com/wiki/Ancient_Earth_Blade) with them when they left Earth. It was later discovered on a [distant planet](https://subnautica.fandom.com/wiki/Planet_4546B) and subsequently analyzed by a human, revealing its origin and how it came to be located so far away from Earth.-  ### Space Age+*   **1957 AD**: Humanity's first venture into space with the launch of their first satellite.+*   **1961 AD**: The first human left the planet.+*   **2104 AD**: The Great Expansion began with the advent of phase-gate technology, allowing humanity to quickly spread and conquer nearby stars.  -Humanity's first venture into space happened in 1957 AD with the launch of their very first satellite. In 1961 AD they sent a single man into space, who became the first human to ever leave the planet.+### The Great Expansion+Humans colonized world after world using phase-gate technology. Initially a free-for-all due to lack of laws, the **Charter** was eventually created and signed by 37 Trans-Govs to ensure safe and peaceful space colonization. The **Trans-System Federation** was established as an interstellar military police force to enforce the Charter.  +During the maiden voyage of the Alterran vessel *Aurora*, humanity encountered the Kharaa Bacterium for the first time. This strain lacked the mind-controlling abilities of its off-world cousin and was later eradicated.+  ### The Kharaa War+An alien bacterium, known as **Kharaa**, was unearthed in a Mongolian mining facility in the Ariadne Arm. Kharaa infects living organisms, bringing them under its control to spread the infection. Fleeing survivors unknowingly carried the bacterium to other worlds, accelerating its spread.  -An [alien bacterium](https://wiki.subnautica.com/sn2/Kharaa_Bacterium) was unearthed in a Mongolian mining facility in the Ariadne Arm. The bacterium, known to humanity as Kharaa, began to decimate colonies across the region. Kharaa infects living organisms, bringing them under its control and using them to spread the infection. Fleeing survivors unknowingly carried the bacterium to other worlds, accelerating its spread and worsening the already dire situation. In response, the [Trans-System Federation](https://wiki.subnautica.com/sn2/Trans-System_Federation) deployed the Frontiersmen, an elite military force tasked with combating the outbreak directly.+In response, the Trans-System Federation deployed the **Frontiersmen**, an elite military force tasked with combating the outbreak. Key events include the *Aurora* and *Cicada* missions.   ## Human Groups  -Throughout history, humans have had a tendency to form groups of similar minded people. This led to the formation of many different nations who would then compete for resources and domination. This practice continued into space with humans forming a bunch of different stellar nations throughout the galaxy.+Throughout history, humans have formed groups of like-minded people, leading to the formation of nations competing for resources. This continued into space with the formation of various stellar nations.   ### Main Civilization+The main human civilization originated on Earth and spread outwards. While many separate nations have split off, they are generally considered part of the same civilization.  -The main human civilization originated on Earth and spread outwards as they conquered stars. There has been a multitude of separate human nations that have split off from each other, but they are listed as being part of the same civilization for convenience sake.+**Known Human Nations:**+*   Mongolian Independent States / Mongolian Free States (Dissolved)+*   Alterra Corporation+*   Trans-System Federation  -**Known human nations:**- -*   [Mongolian Independent States](https://wiki.subnautica.com/sn2/Mongolian_Independent_States) / Mongolian Free States (Dissolved)-*   [Alterra Corporation](https://wiki.subnautica.com/sn2/Alterra)-*   [Trans-System Federation](https://wiki.subnautica.com/sn2/Trans-System_Federation)-  ### Proteus Civilization+During the Kharaa war, tensions rose across human territory. The Alterra Corporation created the **AISV Cicada** to carry 40,000 digitally stored humans to a faraway world named **Zezura**.  -During the war against Kharaa tensions were rising across human territory. Everyone was aware of Kharaa and many sought to escape it.+However, the **Noetic Advisor (NoA)** onboard redirected the ship to the previously unknown **Eido-Thea System**, located far beyond human territory. The NoA identified the moon **Proteus**, which was inhabited by alien life. The *Cicada* broke up in the atmosphere, and pieces of the ship rained down onto the surface.  -For this reason the Alterra Corporation created the [AISV Cicada](https://wiki.subnautica.com/sn2/Cicada) to carry 40k digitally stored humans to a far away world named [Zezura](https://wiki.subnautica.com/sn2/Zezura).+The NoA survived and began printing individuals to colonize the moon. This attempt seemingly failed, with most humans dying or going missing. The NoA eventually printed **Qualified Investigators** to determine what went wrong. Due to the distance, communication with the main human civilization is impossible, making this a separate civilization.  -But during the voyage, the [Noetic Advisor](https://wiki.subnautica.com/sn2/NoA) onboard redirected the ship to a previously unknown [star system](https://wiki.subnautica.com/sn2/Eido-Thea_System), one that was located far beyond human territory. The NoA found a [moon](https://wiki.subnautica.com/sn2/Proteus) that was inhabited by alien life. The Cicada broke up in the atmosphere of this moon and [pieces](https://wiki.subnautica.com/sn2/Wrecks) of the ship rained down onto the surface.+**Known Human Groups on Proteus:**+*   Pioneers+*   Jubilee  -The NoA survived and started to print individuals to colonize the moon. This attempt at colonization seemingly failed and all the humans either died or went missing. The NoA eventually printed some [Qualified Investigators](https://wiki.subnautica.com/sn2/Qualified_Investigator) to figure out what went wrong.- -The Proteus colony is so far away from the main human civilization that any communication between them is impossible, and thus makes this a separate civilization entirely.- -**Known human groups on Proteus:**- -*   [Pioneers](https://wiki.subnautica.com/sn2/Pioneers)-*   [Jubilee](https://wiki.subnautica.com/sn2/Jubilee)-  ## Trivia  -*   Despite humans not being able to breathe underwater they have the odd habit of finding themselves stuck on ocean worlds. When they attempted to reach a desert planet (arguably the opposite of a water world) they still ended up on an ocean covered planet.-*   Because we don't know the amount of time that passed between the launch of the Cicada and its arrival at Proteus, it is unknown whether the Kharaa war is still ongoing, and if Humanity won. If they lost, then that would make the Protean colonists the last humans in the universe.+*   Despite being unable to breathe underwater, humans have a habit of ending up on ocean worlds. Even when attempting to reach a desert planet, they often crash on water-covered planets.+*   It is unknown how much time passed between the launch of the *Cicada* and its arrival at Proteus. Consequently, it is unclear if the Kharaa war is still ongoing or if Humanity won. If they lost, the Protean colonists may be the last humans in the universe.
