- "Humans. Violent but peace-loving. Passionate but cerebral. Humane but cruel. Impulsive but calculating. Generous but selfish. Humans. Altogether a contradictory and deeply flawed species. And yet... And yet, somehow I knew that they represented the best hope of the galaxy. Perhaps the only hope."
Humans are the dominant species of Earth. They are the latest victims of the Yeerk Empire. The Yeerks had targeted humans because they were numerous, comprising of billions of potential hosts, as well as the species being unaware of the existence of other sentient life forms. According to Aximili-Esgarrouth-Isthill, it is possible that the Yeerks also feared humans due to their ability to adapt and learn rapidly. Humans have a distant cousin that live in the ocean known as the Nartec, a race of aquatic humans.
