The differences between divergent and convergent evolution is that divergent is when they share the same ancestor but have evolved differently. Whereas convergent is when animals with different ancestors manage to develop or evolve the same. Here is a for instance sharks and dolphins have developed fins and gills to suit them in there environment. here is another example of how they differ divergent is when an animal adapts or evolves due to the environment. Convergent on the other hand is similar but it is when another animal has a similar trait like insects and birds both of them developed wings but if you were to look at it you would see that the wings differ is by what they are made out of like birds are from there exoskeleton and has feathers but the insects are membranous outgrowth with nervules from the haemocoelom.
