Zoology Review: What's Gnu?

About Zoology, from BoardGameGeek:

When the pages of the Great Encyclopedia Zoologica burst open, the wild is unleashed and only sharp minds can restore order. The Great Encyclopedia Zoologica has cracked, scattering creatures from alpacas to platypuses into a chaotic world where instincts run wild and facts matter more than ever. In Zoology, you become a team of curious and quick-witted zoologists, trying to identify animals based on clues and characteristics before the Age of Discovery slips into an Age of Chaos. Zoology is a 2-6 player deduction game where you become zoologists identifying animals scattered from the Great Encyclopedia Zoologica. Players secretly receive an animal card (visible only to others) and must deduce their own identity by asking comparative questions about characteristics, appearance, and behavior. The game blends analytical thinking and clever communication into a lively 15-30 minute puzzle. Play competitively to identify your animal first, or co-operatively to identify all animals within a turn limit. Optional modules and fun facts add variety to this social deduction challenge. -description from the publisher
