How does Paticcasamuppada or 12 Links of Dependent Origination relate to Aversion?

Buddha mentions in the Paticcasamuppada that craving leads to clinging and this leads to existence ,birth and death. In other places Buddha mentions that Aversion is a very unwholesome state of mind and we should practice to remove it from our mind. However, I would like to know how aversion plays a role in the 12 links of dependent origination as only craving and clinging are mentioned.
