Species of modern stick and leaf insects belonging to the order Phasmatodea are similar to 47-million-year-old fossils of stick and leaf insects. Researchers think that the similar forms of these insects indicate that ancient insects may have engaged in one of the same behaviors as modern insects to escape predators. This behavior, called catalepsy, involves remaining extremely still to deceive predators. This scientific explanation regarding stick and leaf insects indicates that they A
developed a successful survival strategy over the course of 47 million years that decreased their reproductive success.

B
have lived in a stable environment that did not undergo significant change over 47 million years.

C
developed a successful survival strategy 47 million years ago, increasing their reproductive success.

D
have passed mutated genes to each generation, impairing their ability to evolve for 47 million years.
