Everyone's opinions are different and we all read for different reasons, but just because an article isn't a strictly factual, question->answer piece doesn't mean it's poorly written. As the article makes clear the answer is still unknown, therefore the purpose of the piece is to both show how science is done, even when it doesn't go as planned, and to get the reader thinking about something they may have never considered before about an animal many of us spend a lot of time with.
