Evolution: Stink bug guts reveal DNA surprise

From the New Scientist: The gut bacteria of the humble stinkbug could reveal intriguing insights into the evolutionary origins of disease-causing bacteria, researchers say.

...To their surprise, the stinkbug DNA family tree pattern proved identical to the bacterial DNA family tree pattern, revealing that the bacteria and the stink bugs evolved in lock-step.
