There are two types of species effectively, the first being of course the aliens of which there are many. The second type, GMS's or genetically modified strains are people modified using one of several groups of artificial viruses to create what is in effect a different species.

The Tol-Racine were the first species that made contact with human in 2051. Luckily for humanity the much more advanced Tol-Racine were(and are) involved in a bloody civil war. The first contact was with a nearly destroyed cruiser that a frigate managed to save the crew off of. Although the cruiser was a rebellion ship, the act of saving the crew was eventually viewed by both sides of the conflict as a sign of possible future cooperation and may have saved humanity from the often warlike people.
The Tol-Racine are in many ways similar to humans, varying from rabid isolationists to equally extreme xenophiles. They are however a hard people who turn to violence early in conflict resolution and have thus had a long history of war with several other species and have maintained an on going civil war for more then 200 years.
