The phenomenon raises evolutionary questions that he continues to study.

At the same time, evolutionary questions are still being actively researched by biologists.

"I'm only a molecular biologist," he said, implying that deep evolutionary questions were beyond him.

"The more precisely we can resolve time, the more sophisticated the evolutionary questions we can address."

This situation represents a case of animal signaling where there arises an evolutionary question to explain the maintenance of the signal.

The papers reveal in part Parsons' early interest in social evolutionary questions.

"Research designs that address evolutionary questions about medical disorders."
