What contrast exists between the deep evolutionary success of *Blattodea* and the success of the German cockroach?

Answer

Deep success relies on longevity, while the German cockroach's success relies on rapidly exploiting niches created by humans.

The long evolutionary success of the order depends on general adaptation over hundreds of millions of years, whereas the ubiquity of the German cockroach is tied to rapid adaptation linked to human trade and settlement in recent centuries.
