The study — which Knapp refers to as her "calls-and-balls paper" — had its genesis in trips she took to Central and South America, where she would hear howler monkeys giving noisy examples of how they earned their name and wonder what the sounds were all about.

So being a female... er... being a scientist, she decided that the way to find out was to go for the balls.

Of course.
