@jonychoren A common chimpanzee is sitting atop a pile of books and manuscripts. The subject is holding in its right hand a human skull, echoing the scene in Shakespeare's Hamlet where the Prince of Denmark mourns Yorick ("Alas, poor Yorick! I knew him…"). The chimpanzee cradles its chin with a hand in a contemplative posture. Sitting with its left leg supporting the right, the right leg holds the calipers in its foot. A spine of one of the closed books reads "Darwin".
