Which of the following does not support the idea of descent with modification? A. Organisms and the cells that they are composed of arise from DNA B. When organisms reproduce they generate new copies of DNA to pass down to their offspring C. We inherit traits from our ancestors because in possess molecules of their DNA that you received from your parents D. In the process of DNA replication, mutations occur with the goal of increasing an organism's fitness
