The author proposes that lateral gene transfer can explain some of the evidence that is discordant with the traditional universal ancestor model. Analyze the role of lateral gene transfer at three different stages along the path of evolution. Use this statement rom the author to describe the stages "Evolution at the subcellular level can be viewed as a bridge between modern organismal evolution and the much earlier evolution that involved organic chemicals in an abiotic world."
