Human

A few million years later, another species has evolved from Cavemen, called Human. Otherwise known as the modern human. Unlike Cavemen, Humans are characterized by upright posture and bipedal movement; manual dexterity and increased tool use, compared to other animals; and a general trend toward larger, more complex brains and societies. With said brains, they are capable of high levels of abstract reasoning, language, problem-solving, sociality, and culture through social learning.          Industry[1] also starts in this age. Many generators are invented such as:    Hydroelectric Plants,  Windmills,  Steam Engines,  Fusion Reactors... These inventions improve and enhance their life.
