The prediction supported by the data in the table is:
The amino acid sequences for flowering plants and cone-producing plants will be the most similar.
This is because flowering plants and cone-producing plants share a more recent common ancestor (250 million years ago) compared to the common ancestor between flowering plants and green algae (500 million years ago). Therefore, it is expected that the amino acid sequences of the proteins from the flowering plants and cone-producing plants would show greater similarity due to their closer evolutionary relationship.
