Archeaopteryx

Mina is drawn to birds. She constantly observes them carefully, draws them, and models them. The birds are a symbol of freedom, which shows that she desires nothing more than the freedom of her mind. Michael, on the other hand, only looks at the birds more closely when Mina asks him about the color of a blackbird, which shows that until then, Michael did not feel the desire to let his thoughts flow freely. The birds are also a symbol of evolution. Mina shows Michael a picture of the Archaeopteryx, the earliest fossil of a bird, and explains how the body and bone structure have changed to enable birds to fly freely.
