This is generally true in phylogenetic studies where birds and crocodilians share a more recent common ancestor with each other than either does with lizards. This relationship places birds and crocodiles together in a group known as Archosauria. This reflects the consensus view based on both morphological and genetic studies, indicating that crocodiles are more closely related to birds (both being part of the Archosaur group) than they are to lizards, which are part of a different reptilian lineage.
Problem:
By reference to the tree below, which of the following is an accurate statement of relationships?
A) A crocodile is more closely related to a lizard than to a bird
B) A crocodile is more closely related to a bird than to a lizard
C) A crocodile is equally related to a lizard and a bird
D) A crocodile is related to a lizard, but is not related to a bird
