In the wheel of life, how can death be a condition for ignorance?

Considering the 12 nidanas as represented on the Tibetan wheel of life. I can understand how the previous links cause (or condition) the subsequent ones for instance sensation is a condition for craving. However as the wheel turns it does birth -> conditions -> death -> conditions -> ignorance In what way is death a condition for ignorance? I can't see a casual link there.
