What's your animal IQ?

Scientists claim they have finally discovered the answer to the age-old question: Which came first – the chicken or the egg?

Researchers at the university of Sheffield and University of Warwick have identified that a protein called ovocledin (OC-17) is crucial in the formation of egg shells and is produced in the pregnant hen's ovaries. And therefore, the answer must beÂ…The chicken! What they've not yet proved is how the protein-producing chicken existed in the first place. Back to the lab then! 

But never mind chicken and eggs. How's your knowledge of the rest of the animal kingdom? Are you as smart as an owl, dumb as an ox, or just plain silly as a goose? Take the animal IQ quiz and find out!
