The video is for anyone who is interested in the subject in general. The topic is speciation and Coyne is one of the world's leading experts on the subject, having written a detailed textbook on the matter ( https://www.cell.com/current-biology/comments/S0960-9822(04)00541-X ). So in that way, it's relevant to the discussion on speciation.
When you want specific examples, what do you mean exactly? Are you expecting to see species separating in real time? Obviously you can't see that, because the time scales involved are generally vast. The mathematical modeling you highlight is part of the process of understanding the mechanisms involved. As I said, it's not a simple matter:
But back to the point I made about vast time frames, perhaps not necessarily:
