i will probaly answer with this guy:

divergent evolution is where closely related organisms evolve to be very different over time due to isolation in different environments. ie Darwin's kinches has various sized beaks due to different environmental resources. here Natural selection acts upon similar genetic material but selects different adaptive variations due to different environments. hence these organisms evolve to be very different over time.
