Often answers to the simplest questions are the most insightful. Take for instance the perfectly reasonable query, ‘why are there so many kinds of plants?’. This fascinating question is pondered by Professor Fred Essig (University of South Florida, USA) in his guest blog entry at Biology Online, a site that claims to provide answers to all your biology questions. I won’t give away the answer, but taking a niche-based approach Essig provides a thoughtful response that can be used by all should the same question come up in your own teaching. Cheers, Fred!
