The actual question was posed much later in the footage than the fake creationist overvoice suggests: The question was, "Can you give an example of a genetic mutation of an evolutionary process which can be seen to increase the information in the genome?"
This is a question that requests predictions from now to later. The genome has changed through evolutionary time, and we can see the traces of that change in accumulated differences, for example, in the genes coding for identically functioning but structurally modified proteins. We can see the traces, for example, in gene duplications that are present in organism higher up the evolutionary scale but absent in more primitive organisms.
The problem with the question is that we cannot know whether genetic variation that we observe now can be expected to lead to species diversification. Organisms display a range of genetic differences between individuals of the same species, yet only time will tell which of those genetic endowments might confer survival advantage to its bearer and hence persist and prosper in the future. That would be like looking at a newborn infant and speculating on the appearance of his or her great-great-great-grandchildren.
