Human

Humans are the native, sapient species of Earth.

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.

The life expectancy of humans has varied throughout the years. In the late-18th and early-19th centuries, the average life expectancy was around 30 to 40 years. However, medical advances over the centuries have led to an expectancy of around 100 years by 2016.

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.
