Multiple Choice

The same DNA code is used by Archaea, Bacteria, and Eukarya.However, when the sequences of genes encoding proteins of similar function are compared, certain groups of genes in Eukarya are more similar to those in Archaea than to those in Bacteria, while other groups of genes in Eukarya are more similar to those in Bacteria than to those in Archaea.Which statement is consistent with these findings?

• A) The origins of Archaea, Bacteria, and Eukarya are all different and unique from one another.
• B) Archaea and Bacteria have the same common ancestor that differs from the one each shares with Eukarya.
• C) Eukarya and Bacteria have the same common ancestor, and Eukarya and Archaea have the same common ancestor, but Archaea and Bacteria do not share a common ancestor.
• D) Archaea, Bacteria, and Eukarya represent lineages that came from a single common ancestor.
• E) Eukarya and Archaea have the same common ancestor that differs from the one each shares with Bacteria.
