Human

Humans are a sentient species, native to the planet Earth. They are the majority of the Terran Federation populace and achieved interstellar flight in the early-22nd century.

Biology
Humans have a fairly robust physiology. Their internal makeup and reproductive processes are typical of most bipedal mammals, and their size and proportions give the appearance of being strong, fast and agile.

Humans can live to about 150 years, and recent medical advances have eradicated almost all known diseases that afflict them.

Humans reach physical maturity at approximately eighteen years of age, at which point they have usually finished their academic education and either directly enter the workforce or begin training for a profession.

Despite the substantial genetic diversity of humans, certain physical traits have been becoming more rare ever since the 19th and 20th centuries, when the mixing of different Earth ethnicities, due to social progression and acceptance, became more commonplace. To this end, with the merging of genetics, certain traits have declined in frequency.

Culture
Humans are generally seen to be very intelligent, abnormally ambitious, highly adaptable, individualistic and thus, unpredictable. They have a powerful desire to advance and improve themselves, and do so with restlessness and relentless curiosity.
