The more you learn about a topic, the more questions you can ask about it. The scientists on B.C.I. are experts in these topics, so they have lots of questions to investigate while they're here. They spend years learning about a specific tree, ant or snake because they are passionate about what they study. I'm still figuring out what kind of animals I want to study after I finish my work here with the kinkajous, but I don't think it's going to be an insect.
