If additional DNA sequence evidence shows that yeast genes for synthesising proteins are more similar to protein-synthesising genes in bacteria than those in archaea, a modern systematist would ________.
A) redraw the phylogeny to show eukaryotes sharing a more recent common ancestor with bacteria than archaea
B) redraw the phylogeny to show more recent common ancestry between archaea and yeast than between eukaryotes and archaea
C) retain the phylogeny that shows a more recent common ancestor between eukaryotes and archaea
D) retain the phylogeny that shows a more recent common ancestor between bacteria and archaea

If additional DNA sequence evidence shows that yeast genes for synthesising proteins are more similar to protein-synthesising genes in bacteria than those in archaea, it suggests that eukaryotes share a more recent common ancestor with bacteria than archaea. Thus, a modern systematist would redraw the phylogeny to show eukaryotes sharing a more recent common ancestor with bacteria than archaea.
