2. adaptive radiation is an example of divergent evolution.it is an evolution of different species from a single point radiating in different geographical area.
example..darwin's finches
they are seen in galapogan's island
they are small birds and there are 20 types of them.
variations was seen in their beaks
later it was concluded that......... they can't interbreed among themselves
conclusion:they had a common ancestor
b'cz galapogans was a microhabitat,beak was modified on the basis of what they eat.for egs:seed eater,gram.nut or insect eater....the ancestor was concluded to be a seed eater.
another examples are........australian marsupials , placental mammals etc..........
