Humans

Humans are a Class 1 civilization from Earth, locked in constant wars amongst their own.

History
Human being, a culture-bearing primate classified in the genus  Homo , especially the species  H. sapiens. Human beings are anatomically similar and related to the great apes but are distinguished by a more highly developed brain and a resultant capacity for articulate speech and abstract reasoning. In addition, human beings display a marked erectness of body carriage that frees the hands for use as manipulative members. Some of these characteristics, however, are not entirely unique to humans. The gap in cognition, as in anatomy, between humans and the great apes(orangutans, gorillas, chimpanzees, and bonobos) is much less than was once thought, as they have been shown to possess a variety of advanced cognitive abilities formerly believed to be restricted to humans.
