 ![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.+Humans are terrestrial mammals that utilize bipedal locomotion and have four limbs. They breathe oxygen and exhale carbon dioxide. 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, individuals may have radically different genes.  -*   **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.+Humans are biologically compatible with a wide array of alien lifeforms, enabling them to digest alien food and contract alien diseases. However, unmodified humans cannot survive in the deadly environment of the moon Proteus without assistance or modification.  -> **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.  -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 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. This artifact was later discovered on a distant planet and analyzed by Ryley Robinson, revealing its origin.   ### 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 occurred in 1957 AD with the launch of their first satellite. In 1961 AD, they sent a single man into space, becoming the first human to leave the planet.+ +With the advent of phase-gate technology, humanity began to quickly spread and conquer nearby stars. The **Great Expansion** began in 2104, marking a new era of interstellar colonization.+  ### 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.+Humans colonized world after world using phase-gate technology. Initially, space colonization was a free-for-all due to a lack of laws. Eventually, the **Charter** was created and signed by 37 Trans-Govs to ensure safe and peaceful colonization. The **Trans-System Federation** was established as an interstellar military police force to enforce these laws.  +During the maiden voyage of the Alterra 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 due to the actions of two individuals.+  ### 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.  -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.+An alien bacterium known as **Kharaa** was unearthed in a Mongolian mining facility in the Ariadne Arm. The bacterium began to decimate colonies across the region, infecting living organisms and bringing them under its control to spread the infection. Fleeing survivors unknowingly carried the bacterium to other worlds, accelerating its spread.  +In response, the Trans-System Federation deployed the **Frontiersmen**, an elite military force tasked with combating the outbreak directly. The *Aurora* and *Cicada* missions were launched in chronological order during this crisis.+  ## Human Groups  -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.+Throughout history, humans have formed groups of like-minded individuals, leading to the formation of nations competing for resources and domination. This practice 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 outward.

The Alterra Corporation created the **AISV Cicada** to carry 40,000 digitally stored humans to a faraway world named **Zezura**.  -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.+During the war against Kharaa, tensions rose across human territory. To escape the outbreak, the Alterra Corporation created the **AISV Cicada** to carry 40,000 digitally stored humans to a faraway world named **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.+During the voyage, the **Noetic Advisor (NoA)** onboard redirected the ship to the previously unknown **Eido-Thea System**, located far beyond human territory.

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 extreme distance, communication with the main human civilization is impossible, making this a separate civilization.+  **Known Human Groups on Proteus:**-*   Pioneers-*   Jubilee  +*   **Pioneers**: Early colonists printed by the NoA.+*   **Jubilee**: A group of survivors/colonists on Proteus.+  ## Trivia   *   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.+*   It is unknown how much time passed between the launch of the *Cicada* and its arrival at Proteus.
