Scientists have been able to reconstruct DNA sequences in an ancestral archosaur to produce an opsin protein.Knowledge of the opsin sequence in the ancestral archosaur provides clues about the animals' visual capabilities and probable behaviors.Which is conclusion based on their results is false?
A) The ancient archosaur was probably nocturnal.
B) The ancestral state for this protein could not be recreated.
C) Phylogenetic analysis allowed scientists to reconstruct the change(s) in opsin.
D) The opsin protein of the archosaur was shifted to the red end of the spectrum.
E) Phylogenetic analyses can be used to reconstruct extinct species.

Question

The statement that the ancestral state for this protein could not be recreated is false because the scientists were able to reconstruct DNA sequences to produce an opsin protein, indicating they could recreate the ancestral state of the protein.
