6. 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 from the author to describe the three 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.” (4 points)

Ry was studying two populations of the same species of lizards. one population lived on an island and the other lived on the mainland. both populations were affected by a hurricane that hit the island and the mainland with equal force. a year later, henry was testing the gene frequency and saw a decrease in genetic variation in the island species, but not in the mainland species. which best describes a conclusion he might have reached? gene flow greatly affects small populations, but large populations can recover. genetic drift greatly affects small populations, but large populations can recover. gene flow greatly affects large populations, but small populations can recover. genetic drift greatly affects large populations, but small populations can recover.
