Question
Tendrils in plants are an example of
- Convergent evolution
- Radiation
- Divergent evolution
- Co-evolution
The correct answer is: Divergent evolution
Leaves modified as thorns 
tendril 
are homologous structure. The homologous organs show divergent evolution.
Analogous organs show convergent evolution. Coevolution involves evolutionary changes in one or more species in response to changes in other species of the same community.
