It turns out that evolutionary change doesn't so much depend on how many generations there have been (because things tend to be well enough adapted to their environment that obvious changes don't help much), but rather on how much their environment has changed around them.

That said, the amazing diversity of beetles suggests that some types of bugs have indeed been changing rapidly.

Of course. Number of generations is merely one step less irrelevant than the amount of time that has passed.

As with most things there is a nearly tower of progressively more accurate statements that could be made.
