The Newborn is a new breed of Xenomorph, which perfectly combines the DNA of a Human and a Xenomorph into a highly efficient killing machine. It was created when scientists of the United Systems Military cloned the body of Ellen Ripley from DNA apparently removed from her upon her crashlanding on Fiorina 'Fury' 161, which contained a developing Xenomorph Queen (although how her own DNA could contain that for the Queen is unknown). Once removed, the Queen continued her cycle of laying eggs, but developed a second stage, which involved the creation of a womb - inherited from the DNA exchange from Ripley.
