Why elephants have big ears Book

This was an engaging book on a topic that I honestly hadn't really considered before, although once I realized the question of the book I was all in. It was an interesting exploration of the theories surrounding warm-bloodedness vs. cold-bloodedness, starting with a question with a "well, duh" answer (Q: Why do elephants have big ears? A: thermoregulation) and using that question and answer as a doorway into the rabbit hole of comparative morphology, survival strategies, dinosaurs, birds, competition, and invasive species all involving thermoregulation as a central theme. While my eyes did glaze over through some sections, that's unfortunately a risk in any book after a certain level of scientific involvement. This book would be readable for people without a background in biology, but they may need to look up a few things as they are mentioned in the book for a better understanding of some topics. Overall it was an interesting book exploring a topic that I (and I'm sure many others) take for granted, and I'm glad I took the time to read it.
