Darwin's monkey "Wallace" is a reference to the naturalist Alfred Russel Wallace who independently developed the idea of natural selection. Darwin and Wallace presented the theory together, but due to the publication of "On the Origin of Species" Darwin usually gets sole credit for the theory. The scene on Butterfly Island when Darwin closes Wallace in the sack and says " we.... I have an idea" alludes to him taking sole credit for ideas that were not completely his own.
