What organism on this diagram would have DNA most similar to the penguin?

Answer explanation

The lines to chicken and penguin meet at a "V", which indicates their common ancestor. Ducks and pigeons are also birds, but they are more distantly related from the penguin.

What conclusions can be made based on this table shown?

• the American black bear and the giant panda share a more recent common ancestor

• the giant panda and the red panda share a more recent common ancestor

• the red panda and the racoon share a more recent common ancestor

• the giant panda and the racoon share a more recent common ancestor
