Humans were a species of bipedal primates in the family Hominidae (taxonomically Homo sapiens, Latin for "wise human" or "knowing human").
Humans had a highly developed brain, capable of abstract reasoning, language, introspection and problem solving. This mental capability, combined with an erect body carriage that freed the forelimbs (arms) for manipulating objects, allowed them to make far greater use of tools than any other species on Earth.
DNA evidence indicated that modern humans originated in the east of the African continent about 200,000 years BC.
Soon members of the human were distributed planetwide, with large populations inhabiting every continent on except Antarctica. As of that time, they were a dominant form of biological life, in terms of their distribution and effect on the biosphere.
With the creation of spacefaring technology, humans began to colonize a number of planets surrounding their own solar system, like Crestwell's World in the Crestwell's Star System. However, it did not take long for them to discover that another advanced civilization had evolved on one of the worlds in their reach, but had been completely wiped out by another one. This third race, which somebody named the Gbaba, would obviously be a great threat to humanity, so that a military build-up began on most worlds of the Terran Federation. On July 2, 2378, the Gbaba arrived, and within half a century, they destroyed the Federation and all but wiped out the human race.
