some people get stuck on islands with food no other than fruits, so they have no choice but to become frugivores

"When it comes to interactions among living organisms and their environment, the real classroom is the world outside, not the pages of a biology textbook."
Nature is kind of a lab itself, maybe the best and most useful laboratory, and museum.
