Humans are the galaxy's most numerous and politically dominant sentient species with millions of major and minor colonies quadrant-wide. Like most of the galaxy's sentient species, Humans had a torso, two legs, two arms, and one head. Other sentient species with a body type roughly similar to Humans were often referred to as humanoid, since Humans were the most common example. Their heads had two eyes, one nose for breathing and smelling, and a mouth for eating, breathing and communicating. Human arms had five-fingered hands for manipulation, mirrored by their legs' five-toed feet. Also, like most species, they came in two sexes, male and female.
