During prophase, the nuclear envelope surrounding the DNA starts to disappear and the DNA condenses into chromosomes<span>. The 46 </span>chromosomes each<span> consist of 2 identical sister chromatids. The centrioles move to opposite poles of the parent cell. The second step of </span>mitosis<span> is metaphase.</span>
Darwin could compare only the anatomy and embryos of living things. Today, scientists can compare their DNA. Similar DNA sequences are the strongest evidence for evolution from a common ancestor. Look at the diagram in Figure 9.3
