I believe it is behavioural isolation. When there are changes within a certain species, e.g. new birdcalls are formed in certain individuals in a species, "traditional" birds may not like such mating calls and only choose to mate with the more common birdcalls from majority of the birds. There are also some birds that may like the new birdcalls, and choose to mate with birds with those birdcalls. They become genetically isolated as they continue such behavior. Eventually, through genetic drift and other mutations, different species form from a single specie.

To be honest, Niklesh, I hold a firm doubt that somebody will want to do this work for you unless they have been assigned it–especially since social media is so prevalent today.
If you disagree with the assignment and can veer off a little, I'd suggest writing a conversation about how responsible use of social media benefits teenagers and helps connect the world.
a few good points for this would be:
• Networking with people in higher places is especially important for entrepreneurship and job searching (SEE: LinkedIn)
• Social media helps bring people with similar interests from across the globe together
• Social media allows people to communicate experiences, events, and just communicate when physical interaction is difficult to attain
