The accumulation of mutations in DNA is the basis for evolution and organismal divergence. The amount of divergence can be measured by comparing the sequences of homologous genes. Which of the following statements is most likely to be true? Choose one:A. Although animals and fungi diverged over 1 billion years ago, it is possible to learn about the function of human genes by studying their homologs in yeast.B. Although ~70% of human genes have detectable sequence homologs in the nematode C. elegans, it is likely that they serve different functions, since humans and worms are so different from each other.C. Mice and humans are both mammals, and so we can expect that every mouse gene has a homolog in humans, and biologically, our cells behave the same.D. Bacteria and humans have diverged so far that it is unlikely that they have any recognizably homologous genes at all.
