Human

Humans are the only sapient species to evolve on the planet Earth in the Sol system (Sol 4.7.0.0.0.0//3). As their homeworld has significantly varied climates and a high degree of seasonality caused by a significant axial tilt, Humans are adapted to a broad range of environments, and are known for being able to settle in almost any environment with relatively little technological adaptation. As of the most recent Imperial census (365B0) there were 256,113,303,815 Humans, with 8,104,664,110 of those (3%) living on their homeworld, Earth. 17 Humans have served as Emperor.

Biology
Humans are considered to be the archetype for Type 1 Bipeds, which feature bilateral symmetry with two arms, two legs, an attached abdomen and chest, one neck, and one head. The term “humanoid” (as translated into various vulgar languages) was once popular but is today considered derogatory by most. Their skin, largely but not entirely hairless, ranges through various shades of brown depending on exposure to sunlight. Their hair can be one of several textures and while black, brown, and white are the most common colors, others colors such as yellow, orange, and red are possible.

Humans are omnivorous and diets vary vastly across different cultural groups. The blood chemistry is iron-based. While there exists great variation in height and weight in the Human population, the average height for a Human is between 12 and 24 units and the average weight is between 216 and 324 units. Humans are capable of building subcutaneous fat deposits to insulate heat and then shedding them as needed. They are viviparous, capable of reproducing year-round, and tend to have relatively high fertility rates for Type 1 Bipeds. The average life expectancy for a Human is 211 standard years, although humans are capable of biologically outliving their physical cognitive function in a condition known as dementia.

The Canadian Anarchy
Canada was a nation that formerly occupied the northernmost third of the North American continent.

Government
The national government representing Humans in the Imperium is known as the Imperial Electorate of Humanity. Before being appointed to the electorate, it was admitted to the Imperium under the name United Human Nations. Human governance is significantly decentralized, among the most decentralized systems in use in the Imperium. Most day-to-day decisions are made by various low-level subnational governments, sometimes as small as on the level of individual segments of urban settlements. The national Human government is a confederation in which the various smaller Human governments have representation. Because of this, there is great variation in legal systems and customs across the various Human settled worlds. Many Humans identify more with their particular settlement or ethnic nationality than with the term “Humanity.”

Technology and Culture
Humans discovered faster-than-light travel in the year 33B97, the most recent species among Imperial Electors to have done so, and were admitted to the Imperium in 34021. Because of their ability to reproduce with ease and both their preference and ability to settle in many different areas resulted in Humanity expanding much more quickly than its peer cohort of other nations admitted to the Imperium at similar times. Humans are anecdotally known as particularly skilled diplomats and negotiators, as a result of needing the skill to navigate between the various different Human ethnic nations. It is these factors that are generally attributed to Humanity’s relatively “quick” rise through Imperial ranks of power until they were appointed Imperial Electors in 351A4.

External Relations
Humans are considered to be the dominant political actor in the rimward Fourth Grand Division, with significant influence over rimward Fifth Grand Division powers such as the Asronians, Fokraxtians, and Voranians, all of which together tend to act as an informal economic and political bloc sometimes known as the “Eastern Rim Four.” Inhabited planets directly under the control of the Imperial Electorate of Humanity numbered 42 in the Imperial census of 356B0, but the number of Human-controlled or Human-majority settlements in Imperium space is estimated to number between 1,728 and 3,456, scattered across seven different Grand Divisions. While no direct Human act of rebellion against the Imperium is on record, armed infighting between Human nations has occurred on several occasions. Three of these necessitated Imperial intervention, the most recent being in 34406.
